[PATCH] netconsole warning fix
drivers/net/netconsole.c:99: warning: initialization from incompatible pointer type
<jamesl@appliedminds.com>
input: Fix hid-core for devices that have less usages than values
in a hid report. We could iterate beyond the end of array of
usages before.
<jamesl@appliedminds.com>
input: Add a new ioctl to hiddev, which allows multiple usages to
be set in a single request. Also fixes sizes of fields
in hiddev structs to use _uXX types.
<vojtech@suse.cz>
input: It looks like the Saitek RumblePad needs a BADPAD entry.

it's both safer and correct.

input: Bail out in atkbd.c if scancode set is changed, don't
reinitialize scancode map. This is even more anoying than
a new keyboard device in the unlikely case of set change.

[PATCH] I2C: i2c-voodoo3.c needs I2C_ADAP_CLASS_TV_ANALOG
The Voodoo3 i2c bus has either a bt869 tv-out chip, or also a tv tuner,
decoder and msp3400. Without I2C_ADAP_CLASS_TV_ANALOG, the i2c clients
would have to do a strcmp of the adapter name to distiguish between the
i2c and ddc adapters. Yes, they should be able to tell if the chip at a
given address is what they are looking for, but in the case of the v3tv
module, which is the v4l device, in the 2.4 kerenl I've got it set to
create a dummy client, and the strcmp is the only way to distinguish the
i2c from the ddc. In the 2.6 kernel, class can be defined, simplifying
things for the v3tv module.

<khali@linux-fr.org>
[PATCH] I2C: New chip driver ported: lm80
Here is a port for the lm80 driver, which supports LM80 chips by
National Semiconductor. The port is mostly the work of Tiago Sousa,
which I reviewed and polished as necessary.
<bunk@fs.tum.de>
[PATCH] I2C: update I2C help text

<dsaxena@plexity.net>
[PATCH] I2C: Support for IXP42x GPIO-based I2C
Following is an updated patch to add support for using the GPIO lines
on an Intel IXP42x SOC for I2C. Changes since last patch include:
- Cleanups as per Jean Delvare's comments
- Rename functions as 42x instead of 425
- Change the comments at the top of the file to better reflect the
purpose of this driver.
This code has been tested with the eeprom client driver and worked
w/o any problems.

[PATCH] I2C: fix space in message
BTW, I found something to be fixed in i2c-core:
<khali@linux-fr.org>
[PATCH] I2C: fix mor rmmod oopses
> Oh nevermind, that's just a dumb driver. It's doing a release_region
> on memory it didn't get. Stupid, stupid, stupid...
While we're at it, what about fixing two other drivers that obviously
have the same problem?
(BTW I didn't get an oops as I tried reproducing the problem, only a
"Trying to free nonexistent resource" in dmesg.)
<khali@linux-fr.org>
[PATCH] I2C: Lowercase chips name
This patch brings the name field of adm1021.c, it87.c and via686a.c in
conformance with the defined standard ("all lowercase, as simple as the
driver name itself").
<khali@linux-fr.org>
[PATCH] I2C: fix Hangs with w83781d
Here is a patch for the w83781d driver that prevents register bits from
being arbitrary changed when we force temp2/3 to comparator mode. Keith
Duthie had been reporting various problems with that driver and finally
found that this arbitrary change was the cause of them. He also tested
this patch, which he confirmed to work.
<khali@linux-fr.org>
[PATCH] I2C: fix it87 sensor type
Here comes a patch by Takeru Komoriya which fixes the way the it87
driver handles temperature sensor types selection.
* Use the same values as the CVS driver and sensors program.
* Better comments.
* Get rid of the old setting method (already gone in CVS).
* Handle invalid values correctly.
<khali@linux-fr.org>
[PATCH] I2C: fix another oops in i2c-core with debug
Some times ago, you fixed an oops in i2c-core when debugging is enabled:
http://marc.theaimsgroup.com/?l=linux-kernel&m=107585749612115&w=2
Looks like you missed that second one:
<khali@linux-fr.org>
[PATCH] I2C: Remove asb100 support from w83781d
Now that we have a separate asb100 driver, we can remove the (bad)
support of it from the w83781d driver. Following patch does this. I've
already cleaned this up in our CVS repository.
<khali@linux-fr.org>
[PATCH] I2C: update for sysfs-interface documentation
<khali@linux-fr.org>
[PATCH] I2C: rename sysfs files, part 1 of 2
Here it is. The associated libsensors patch is here:
http://jdelvare.net1.nerim.net/sensors/libsensors-sysfs-names-1.diff
(not applied yet, on purpose)
<khali@linux-fr.org>
[PATCH] I2C: rename sysfs files, part 2 of 2
Here is the second step of my sysfs renaming plan.
This one does the following renames (as I already announced on the
LKML):
temp<n>_hyst -> temp<n>_max_hyst or temp<n>_crit_hyst
sensor<n> -> temp<n>_type
pwm<n> -> fan<n>_pwm
pwm<n>_enable -> fan<n>_pwm_enable
vid -> in<n>_ref
The associated libsensors patch is here:
http://jdelvare.net1.nerim.net/sensors/libsensors-sysfs-names-2.diff
(not applied yet, on purpose)
Note that the w83781d part is a bit more complex, not only because it is
the only driver to require the 5 changes, but also because at some point
the macros assume that the internal variable names match the sysfs
names, so I had to change them too (better than rewriting the macros,
methinks).
For reference, here is the list of changes, by driver:
asb100:
hyst -> max_hyst (4)
pwm -> fan_pwm (1)
pwm_enable -> fan_pwm_enable (1)
vid -> in_ref (1)
fscher:
pwm -> fan_pwm (3)
gl518sm:
hyst -> max_hyst (1)
it87:
sensor -> temp_type (3)
lm75:
hyst -> max_hyst (1)
lm78:
hyst -> max_hyst (1)
vid -> in_ref (1)
lm85:
pwm -> fan_pwm (3)
pwm_enable -> fan_pwm_enable (3)
vid -> in_ref (1)
lm90:
hyst -> crit_hyst (2)
via686a:
hyst -> max_hyst (3)
w83781d:
hyst -> max_hyst (2)
sensor -> temp_type (3)
pwm -> fan_pwm (4)
pwm_enable -> fan_pwm_enable (1)
vid -> in_ref (1)
There's also a documentation update. There will be one more after that
(to make it more readable, no contents change), and a patch to lm83.c to
bring it to compliance with the (new) standard. (If you wonder why I did
not change it with the other drivers: because it was *already* not in
compliance with the old standard. There's some real work to do for this
one.)

[PATCH] SCSI: Recognize device type 0x0C
Device type 0x0C is RAID, so show it as such
<jeremy@sgi.com>
[PATCH] SCSI: remove some SGI devices from the device list
Some SGI RAID devices identify as being SCSI-3, so they don't need
to be in the scsi_static_device_list any more. I've tested to make
sure that all luns still show up in a sparse, large config.
So I'm proposing removing them. Thanks to hch for the suggestion.

Wonderful. Thanks a lot for all your SMP testing, it's been a big help.
This patch corrects an error in the dequeueing code for UHCI. Improper
locking caused it to hang in the oddball case where an URB was unlinked
even before it had been queued.

This patch re-initializes the UHCI Interrupt Enable register following a
PM resume. Apparently some systems clear the register during suspend,
which causes obvious problems later on.

[PATCH] USB: Return better result codes in UHCI
This patch changes the result code returned by the UHCI driver for a
certain class of errors. Under a number of circumstances a USB device is
obliged to send a response packet within a fairly short turn-around time,
typically 1 - 10 microseconds depending on the bus speed. Failure to do
so is a protocol error and should be reported as such, not as a timeout,
which is really a higher-level concept. I believe the EHCI driver already
does this.
I trust nobody will object to the update this patch adds to
Documentation/usb/error-codes.txt, making this more explicit.
In a vaguely related change, the patch corrects the terminology in a few
comments. The parts of a control transfer are called "stages", not
"phases".

as an array index, causing a NULL deref.

[PATCH] USB Gadget: gadget config buffer utilities
Adds two new gadget-side utility functions, to support a declarative
style of managing usb configuration descriptors. The functions fill
buffers from null-terminated vectors of usb descriptors, which are
simple to build or update.
The "ethernet" gadget driver currently has the most interesting config
descriptors. This uses those functions to replace some complex code with
simpler static declarations; result, it's cleaner. (And it'll be easier
to add RNDIS configurations later, too.)
Memory savings (or cost, depending on config) was less than 50 bytes;
nothing worth worrying about.
<david-b@pacbell.net>
[PATCH] USB: EHCI and full-speed ISO-OUT
This is a minor update to the patch I sent out about a week ago.
The key change is to use the I/O watchdog while doing ISO streaming.
Bernd Porr reports that a VT8235 system needs that; it seems like
IDE activity can interfere with the delivery of USB IRQs.
EHCI periodic scheduling updates.
- Initial version of full speed ISO transaction support. This
should handle OUT transactions, such as those for usb speakers.
For now, it's controlled using an EXPERIMENTAL config option:
* I've run into interesting differences in how different USB 2.0
hub silicon (the transaction translators) handle some older
audio devices. Needs more investigation.
* Interrupt transfer scheduling doesn't yet cope well with schedules
where every slot already has activity. For now, don't plug in
devices like hubs, mice, or keyboards while EHCI is streaming.
- Protect freelist for highspeed ITDs, using spinlock. Could be
an issue for some drivers.
- Kick in the I/O watchdog timer (5 msec) for periodic transfers.
In this case, IDE activity on a VT8235 lost the IRQs which should
have kept the ISO stream active. Queues shorter than 5 msec are
not going to work on all USB hosts.
- Simplified the ISO scheduler: doesn't attempt to re-schedule
after lossage, or to short-circuit scanning. (Rescheduling will
probably come back later ... for now, the "hard" error here is
highlighting problems that need attention.)

[PATCH] USB: add new USB Touchscreen Driver
I have attached a patch which contains a driver and documentation for
the MicroTouch (14-206) USB Capacitive Touchscreen controller. It based
on some older code that I have been using for quite some time now (since
2.4.17). This new version has been completely re-written, and now uses
Linux Input. Greg, It would be great to possibly get it into 2.6.4.
Please let me know if I have it all wrong...
Unfortunately, the X11 mouse driver only seems capable of handling
relative data rather than absolute. Hopefully some one will create a
suitable X11 driver capable of accepting absolute data from Linux
Input. If anyone is aware of one, please let me know. Otherwise, I
will most likely begin some work on a patch for GPM.
Calibration support will be on the way soon, but I'm not sure of the
best way to implement. Perhaps some abstract functions could come
available in evdev which can call vendor specific commands for the
calibration within this driver (and perhaps others).

[PATCH] USB Storage: unusual_devs.h entry submission
here is an unusual_devs.h entry which makes two different USB MP3 players
work with Linux' USB storage driver. They share a core chip, the t33520 USB
flash card controller by Trumpion microelectronics. They also share the same
ID 0x090a:0x1001, which is a "generic" ID for t33520 devices using bulk-only
protocol (0x1002 is for CB).
About the MP3 players:
- I own an apparently unbranded one (sold in masses on ebay.de) which
needs US_FL_MODE_XLATE (and used to need US_FL_START_STOP before its
removal).
- Theodore Kilgore (who created the 0x090a:0x1001 record in the
Linux-USB device overwiew) has a "Trumpion Digital Research MYMP3"
which needs US_FL_MODE_XLATE and an explicit US_PR_BULK.
Of course the different players report the same firmware rev. 1.00,
despite their obviously different behaviour. Ugh.
There are more players with this ID, the "Kaser Yofun 100 MP-3" (also
rev. 1.00) being one. The proposed entry may or may not help them, but
it shouldn't break working ones in any case. It is not unlikely they too
will need US_FL_MODE_XLATE.
Below you'll find my /proc/bus/usb/devices with mounted MP3 player and a
patch against 2.4.25-rc3. Please apply.

[PATCH] USB Gadget: make usb gadget strings talk utf-8
Teach gadget/usbstring to expect UTF-8 strings, not ISO-8859/1 ones.
This just gets rid of an API issue: no hacks needed for non-Western

Current drivers won't notice the API change, they use US-ASCII (which
is a strict superset of both encodings).
Future drivers may want to teach utf8_to_utf16le() about the four-byte
encodings, so they can emit surrogate pairs for those Unicode characters.

The driver model does not support repeated device_add(), device_del(),
device_add(), device_del(), ... calls for the same device. But that's
what happens to an interface's embedded struct device when we change
configurations.
Accordingly, this patch changes the device_add()/device_del() calls for
interfaces to device_register()/device_unregister(). When the interface
is unregistered the new code waits for the release method to run, so that
it will be safe to re-register the interface should the former
configuration be reinstated.
Greg, please check this out to make sure I haven't made some dumb mistake.
It works on my system and it fixes a memory leak in the USB system.

Here's a start. This patch begins the conversion process by adding
usbcore support for cur_altsetting and deprecating act_altsetting.
So long as we assumed that altsetting numbers range from 0 to
num_altsetting-1 and that the number matches its index in the altsetting
array, there was no harm in using act_altsetting. But without that
assumption act_altsetting is merely an invitation to errors. Although the
kerneldoc says that act_altsetting is the _index_ of the active
altsetting, it's all too easy to confuse it with the _number_ of the
active altsetting. Using cur_altsetting instead (a pointer rather than a
number) will prevent that confusion.
Until all the drivers have been converted to use cur_altsetting, the core
will have to maintain act_altsetting in parallel with it. Eventually we
will be able to remove act_altsetting, but fixing all the drivers will
take a while.
Included in this patch:
Add cur_altsetting to struct usb_interface and deprecate
act_altsetting.
Add comments and kerneldoc explaining the changes. Also remove
the comments in front of struct usb_host_config (they seem to
have been left behind when usb_ch9.h was split out) and add
kerneldoc for that structure.
Add usb_altnum_to_altsetting() to help look up altsettings based
on their number.
Convert the usb_set_interface(), usb_set_configuration(), and
usb_reset_configuration() routines to support cur_altsetting
and act_altsetting in parallel. Convert a few others to use
cur_altsetting rather than act_altsetting.
Rename a few local variables to make their meaning a little
clearer. It would be nice to change struct usb_host_interface
to something like usb_host_altsetting, but that's a patch for
another time.

[PATCH] USB: Convert usbcore to use cur_altsetting
This patch continues the work of as209 by converting the rest of usbcore
to use cur_altsetting in place of act_altsetting. The changes required
are fairly small, just in the sysfs attributes and hub configuration.
<stern@rowland.harvard.edu>
[PATCH] USB: Small improvements for devio.c
devio.c doesn't need to be changed to support the new altsetting
mechanism, but while looking through it I noticed a couple of places that
could be improved slightly. Here they are, just removal of some redundant
tests (all altsettings for the same interface are guaranteed to have the
same bInterfaceNumber) and function calls.
<stern@rowland.harvard.edu>
[PATCH] USB: Convert usb-storage to use cur_altsetting
I'm beginning the process of converting device drivers to use

<stern@rowland.harvard.edu>
[PATCH] USB: Convert usbtest to the new altsetting regime
This patch converts the usbtest driver to the new way altsettings work.
The largest change is to remove the assumptions that altsetting numbers
lie in the correct range (a debugging message is logged if they don't but
execution doesn't stop) and that the array is sorted by number.

[PATCH] ia64: Don't assume iosapic interrupt controllers
Some ia64 machines don't use an iosapic interrupt controller (a
flagrant violation of the DIG64 spec), so don't assume it's there in
mca.c. Platforms that provide a ACPI_INTERRUPT_CPEI vector are
responsible for registering its interrupt controller type in platform
specific code, iosapic.c:iosapic_register_platform_intr() does this
for platforms with an iosapic where the CPEI vector is listed in the
ACPI namespace, and on sn2, all external interrupts are assigned the
irq_type_sn type, so this change of assumption should be safe.

[PATCH] I2C: keep i2c-dev numbers in sync with i2c adapter numbers
This makes userspace tools easier to figure out which i2c-dev device is

lot of i2c adapter modprobe/rmmod cycles. That will be fixed up soon.

[PATCH] USB: HCD names, for better troubleshooting
See the attached patch -- which restores the behavior of usbcore
to what it had before "struct device.name" went away, in the

It makes the root hubs say what hardware they're actually using,
in the reasonably typical case that PCI names are in use, rather
than being just generic (and hence almost useless) strings. This
sort of information can really help when troubleshooting.

- Hide SND_OSSEMUL - we can select this when SND_MIXER_OSS, SND_PCM_OSS

[PATCH] SCSI Midlayer initiated START_UNIT
The ipr driver that is currently out for review talks to disk array devices

However, any time the adapter gets reset, these devices end up needing another
START_UNIT. This causes problems with the current error handling and these
devices get taken offline when this occurs. Attached is a patch which will
better handle these devices and issue a START_UNIT from the error handler
when appropriate.

SCSI: Make SPI transport attributes mutable
This adds the final missing piece to the transport attributes: A
published API by which they can be set and retrieved (SPI attributes
only). The sysfs field only appears writeable if the driver supplied a
set method in the attribute template, so unsettable attributes show up
as read only.
The consequence now is that the spi transport attribute class is no
longer a simple exported structure: the driver has to attach to the spi
transport class at module initialisation.
<jejb@mulgrave.(none)>
SCSI: implement transport attributes for 53c700
his patch moves the internal storage of the offset and period to the
transport class and adds methods to set them (there's no need for a get
method since the value in the transport class is exactly what the driver
believes the transport agreement to be).
You can see how this type of use of the transport class is supposed to
work: the driver now has init and exit routines attaching and releasing
the transport class (that's the reason for the Makefile perturbation
because it has to init before its users). The correct attributes are
set up in slave_configure() for negotiation and we now export the period
and offset setting functions.

[PATCH] USB: Remove interface/altsettings assumption from audio driver
This patch updates the USB audio class driver to use the usb_ifnum_to_if()
and usb_altnum_to_altsetting() routines, thereby removing assumptions
about which interface or altsetting is stored in which array entry.
It also simplifies the driver's probe() routine by using the raw
configuration descriptor already loaded into memory instead of reading the
descriptor from the device. Now, either the current driver has a bug and
never deallocates the buffer used to hold the descriptor, or else I've
introduced a double-free error. There's no obvious place where the buffer
gets freed, but it's hard to be certain.
It would be good if someone could try out this patch. I can't test it,
not having any USB audio devices handy. If the double-free error is
present, it will show up when the device is disconnected and the
configuration data is released.

Most ATA host controllers follow a standard layout for the

You're right, it is a mess. Beats me why they didn't use a plain old
"for" statement to do that altsetting loop. Probably the most confusing
part is where the code needlessly resets intf->act_altsetting.
Anyway, this patch sets things right. I haven't tried to compile it, but
any errors ought to be pretty small, obvious, and easy to fix.
My intention was to go through the files under driver/usb (in alphabetical

[PATCH] dc395x [1/5] - formatting cleanups
Formatting cleanups.
- Remove lots of comments that were out-of-date, wrong, or now
described things that had been simplified that much that the
comments were no longer needed.
- Move the "static" definition from a line before functions onto the
same line as the function itself.
- Remove "return;" from the end of void functions.
- Remove braces from around single instructions.
- Merge the declaration and assignment to variables in places where
the followed each other.
- Remove braces from around single statement that obviously didn't
need them.

[PATCH] USB: Remove interface/altsetting assumptions from usb-midi
This patch makes the usb-midi driver use usb_ifnum_to_if(), thereby
removing assumptions about which interface is stored in which array entry.
Similarly, it stores the bAlternateSetting value rather than the array
index for an altsetting entry.
Like the earlier patch for the audio driver, this also changes the driver
to use the in-memory rawdescriptor buffer rather than reading a
configuration descriptor from the device. Unlike that earlier patch, this
time there's no question that the deallocation of the buffer is done
correctly. (I suspect the audio driver just left out a call to kfree.)

[PATCH] USB gadget: dualspeed {run,compile}-time flags
This is the first several autoconfig patches; please merge.
This particular one abstracts dual-speed (high and full)
support.
Support some more autoconfiguration for gadget drivers.
Run-time:
* Add gadget->is_dualspeed flag for controllers to set.
* Tested by "ethernet" gadget, to decide whether certain
operations are errors or not.
* Turned on by net2280.
Compile-time
* Generic CONFIG_USB_GADGET_DUALSPEED, not net2280-specific.
* Used by "ethernet" gadget, to decide whether to
include extra code and data for dual-speed support.
* Turned on by net2280.
The basic idea behind this, and other autoconfig patches yet to come,
is minimizing the controller-specific compile-time configuration
needed by gadget drivers.

This removes several controller-specific compile-time config options;
the others are about to be autoconfigured.
- HIGHSPEED replaced by CONFIG_USB_GADGET_DUALSPEED
- Default to self-powered operation
- There's no UI for remote wakeup
It also uses the new config_buf utilities, so it's a bit easier to see
what's really going on (this driver implements four configurations).

[PATCH] I2C: Cleanup fan_div in w83781d
Here is a proposed patch that cleanups the fan_div code from w83781d.
The original code was obviously taken from the 2.4 driver, but the way
things were done in 2.4 do not make any sense anymore (because we now
have a single value per interface file).
Since fan divisor bits are spread over three different regs with various
bitmask manipulations, I don't think it makes much sense to have a
single function as we do in most other cases. Having three different
functions makes more sense, although they are of course similar. The
size increment is only 581 bytes, I don't think its a problem since it
also makes the code much more efficient and readable too IMHO.
I agree that the original code was working - it was simply doing far too
much work each time one would want to change a fan divisor.
Originally, I took a look at the code because I wanted to fix the fact
that changing fan divisors breaks fan mins. But it looked like a good
cleanup before doing that was required. Once this patch will have been
accepted, I'll work on the other one.
I've tested my patch successfully on a W83781D and an AS99127F rev.1.
Note that this means that one part of the code wasn't tested, because
these are the two chips of the family that do not support divisors
greater than 8. If anyone can test it, please do.

Here it is.
The patch is only one line for 2.6.4-rc2. (I also did a little formatting
adjustment to better comply with CodingStyle)
For the 2.4.26-pre1 kernel, I also backported the return codes correction patch
from Oliver Neukum.
The problem with the write function was that, in non-blocking mode, after
submitting the first urb, the function would return with -EAGAIN, not reporting
to the application that in fact it had already sent "transfer_length" bytes.
This way the application would have to send the data *again* causing lots of
errors.
It did return the correct amount with my first patch, because the writecount was
being updated on the end of the loop. However this was wrong for blocking I/O.
The "transfer_length" local variable is still needed because if we used the
transfer_buffer_length field from the urb, then on a second call to write, if
the urb was still pending (in non-blocking mode), the write would return an
incorrect amount of data written.
Anyway, this time I tested it using blocking and non-blocking I/O and it works
for both cases. Even better, this patch only changes the behaviour for
non-blocking I/O, and keeps the same behaviour for the more usual blocking I/O
(at least on kernel 2.6).

What happens if that class_simple_create() fails? Actually,
class_simple_device_add could fail too, but doesn't seem anybody is

[PATCH] x86-64 merge for 2.6.4
The biggest new feature is fixed 32bit vsyscall (SYSCALL+SYSENTER)
support, mostly from Jakub Jelinek. This increases 32bit syscall
performance greatly (latency halved and better). The SYSENTER for Intel
support required some infrastructure changes, but seems to work now too.
The 64bit vsyscall vtime() just references xtime.tv_sec now. This
should make it a lot faster too.
A fix for some Intel IA32e systems. Also a few long standing bugs in
NMI like exception handlers were fixed.
And a lot of other bug fixes.
Full changeLog:
- Clean up 32bit address room limit handling, fix 3gb personality
- Move memcpy_{from,to}io export to ksyms.c file. This seems to work
around a toolchain bug (Andreas Gruenbacher)
- Update defconfig
- ACPI merges from i386 (SBF should work now, acpi=strict)
- Implement mmconfig support based on i386 code (untested)
- Fix i386/x86-64 pci source file sharing
- Implement ptrace access for 32bit vsyscall page
- Always initialize all 32bit SYSENTER/SYSCALL MSRs.
- Export run time cache line size to generic kernel
- Remove explicit CPUID in ia32 syscall code
- Fill in most of boot_cpu_data early
- Remove unused PER_LINUX32 setup
- Fix syscall trace in fast 32bit calls (Suresh B. Siddha)
- Tighten first line of the oops again.
- Set up ptrace registers correctly for debug,ss,double fault exceptions
- Fix 64bit bug in sys_time64
- Optimize time syscall/vsyscall to only read xtime
- Fix csum_partial_copy_nocheck
- Remove last traces of FPU emulation
- Check properly for rescheduling in exceptions with own stack
- Harden exception stack entries (#SS,#NMI,#MC,#DF,#DB) against bogus GS
- Use an exception stack for machine checks
- Handle TIF_SINGLESTEP properly in kernel exit
- Add exception stack for debug handler
- Disable X86_HT for Opteron optimized builds because it pulls in ACPI_BOOT

- Fix eflags handling in SYSENTER path (Jakub Jelinek)
- Use atomic counter for enable/disable_hlt
- Support 32bit SYSENTER vsyscall too (Jakub Jelinek)
- Don't redefine Dprintk
- Change some cpu/apic id arrays to char
- Support arbitary cpu<->apicid in hard_smp_processor_id (Surresh B Sidda)
- Move K8 erratum #100 workaround into slow path of page fault handler.

driver. This patch fixes the problem.

[PATCH] USB Gadget: add "gadget_chips.h"
This adds standard gadget_is_*() calls. Gadget drivers using

Define gadget_is_*() calls, to help do late binding to USB controllers.
Current gadget drivers expect to know at compile time what hardware
they'll bind to. That's not very friendly to a generic PDA distro,
which might prefer to defer such choices to run time.
These macros let drivers change that code from inlined #ifdefs (ugh) to
normal C statements (looks much nicer), so making those "what hardware"
policy choices at run time gets easier.

Thanks to some great debugging work by Olaf Hering and Marcus Meissner

unusable in the kernel.
Since we had to reinstate the inline syscall code we can go back to
using it for those few syscalls that we call. Especially now with
Randy's syscall prototype cleanup we should be calling them directly
but we can do that sometime later.

Unfortunatly a large portion of the oops reports lack the basic
information about what kernel version the oops is for; it's trivial to just
print this in the oops as well to improve the usefulness of bugreports...

[PATCH] ppc64: fix initialisation of NUMA arrays
From: Anton Blanchard <anton@samba.org>
We were hitting problems on machines with cpu_possible != cpu_online when
NUMA was enabled. The debug checks would trip during scheduler init
because we iterate through all possible cpus whereas we only set up NUMA
information for online cpus.
Longer term we should have a cpu_up hook which sets up its NUMA information
but for now we initalise all possible cpus and memory to node 0.

[PATCH] readdir() cleanups
From: <viro@parcelfarce.linux.theplanet.co.uk>
cramfs and freevxfs explicitly mark themselves readonly (as other r/o fs
do).
afs marked noatime (ACKed by maintainer)
filesystems that do not do update_atime() in their ->readdir() had been
explicitly marked nodiratime. NOTE: cifs, coda and ncpfs almost certainly
need full noatime as we currently have in nfs and afs.
update_atime() call shifted to callers of ->readdir() and out of
->readdir() instances. Bugs caught:
dcache_readdir() updated atime only if it reached EOF.
bfs_readdir() - ditto.
qnx4_readdir() - ditto.

[PATCH] adaptive lazy readahead
From: Suparna Bhattacharya <suparna@in.ibm.com>
From: Ram Pai <linuxram@us.ibm.com>
Pipelined readahead behaviour is suitable for sequential reads, but not for
large random reads (typical of database workloads), where lazy readahead
provides a big performance boost.
One option (suggested by Andrew Morton) would be to have the application
pass hints to turn off readahead by setting the readahead window to zero
using posix_fadvise64(POSIX_FADV_RANDOM), and to special-case that in
do_generic_mapping_read to completely bypass the readahead logic and
instead read in all the pages needed directly.
This was the idea I started with. But then I thought, we can do a still
better job ? How about adapting the readahead algorithm to lazy-read or
non-lazy-read based on the past i/o patterns ?
The overall idea is to keep track of average number of contiguous pages
accessed in a file. If the average at any given time is above ra->pages
the pattern is sequential. If not the pattern is random. If pattern is
sequential do non-lazy-readahead( read as soon as the first page in the
active window is touched) else do lazy-readahead.
I have studied the behaviour of this patch using my user-level simulator.
It adapts pretty well.
Note from Suparna: This appears to bring streaming AIO read performance for
large (64KB) random AIO reads back to sane values (since the lazy readahead
backout in the mainline).

[PATCH] time interpolator fix
From: john stultz <johnstul@us.ibm.com>
In developing the ia64-cyclone patch, which implements a cyclone based time
interpolator, I found the following bug which could cause time
inconsistencies.
In update_wall_time_one_tick(), which is called each timer interrupt, we
call time_interpolator_update(delta_nsec) where delta_nsec is approximately
NSEC_PER_SEC/HZ. This directly correlates with the changes to xtime which
occurs in update_wall_time_one_tick().
However in update_wall_time(), on a second overflow, we again call
time_interpolator_update(NSEC_PER_SEC). However while the components of
xtime are being changed, the overall value of xtime does not (nsec is
decremented NSEC_PER_SEC and sec is incremented). Thus this call to
time_interpolator_update is incorrect.
This patch removes the incorrect call to time_interpolator_update and was
found to resolve the time inconsistencies I had seen while developing the
ia64-cyclone patch.

[PATCH] i386 very early memory detection cleanup patch
From: "H. Peter Anvin" <hpa@zytor.com>
This patch cleans up the very early memory setup on the i386 platform. In
particular, it removes the hard-coded 8 MB limit completely by dynamically
creating the early-boot pagetables rather than having them hard coded.
While I was at it, I changed head.S so that it always sets up a local GDT;
this means among other things that SMP and VISWS are no longer special
cases, and is conceptually cleaner to boot. The VISWS people have
confirmed it works on VISWS.
It also uses a separate entrypoint for non-boot processors since this is
completely kernel-internal anyway. This eliminates the need to set %bx on
boot. (If you think this is a bad idea I can eliminate this change; it
just seemed cleaner to me to do it this way.)
Additionally, zero bss with rep;stosl rather that rep;stosb.

[PATCH] LOOP_CHANGE_FD ioctl
From: Arjan van de Ven <arjanv@redhat.com>
The patch below (written by Al Viro) solves a nasty chicken-and-egg issue
for operating system installers (well at least anaconda but the problem
domain is not exclusive to that)
The basic problem is this:
- The small first stage installer locates the image file of the second
stage installer (which has X and all the graphical stuff); this image can
be on the same CD, but it can come via NFS, http or ftp or ... as well.
- The first stage installer loop-back mounts this image and gives control
to the second stage installer by calling some binary there.
- The graphical installer then asks the user all those questions and
starts installing packages. Again the packages can come from the CD but
also from NFS or http or ...
Now in case of a CD install, once all requested packages from the first CD
are installed, the installer wants to unmount and eject the CD and prompt
the user to put CD 2 in....... EXCEPT that the unmount can't work since
the installer is actually running from a loopback mount of this cd.
The solution is a "LOOP_CHANGE_FD" ioctl, where basically the installer
copies the image to the harddisk (which can only be done late since only
late the target harddisk is mkfs'd) and then magically switches the backing
store FD from underneath the loop device to the one on the target harddisk
(and thus unbusying the CD mount).
This is obviously only allowed if the size of the new image is identical
and if the loop image is read-only in the first place. It's the
responsibility of root to make sure the contents is the same (but that's of
the give-root-enough-rope kind)
<akpm@osdl.org>
[PATCH] loop setup race fix
From: Chris Mason <mason@suse.com>
There's a race in loopback setup, it's easiest to trigger with one or more
procs doing loopback mounts at the same time. The problem is that
fs/block_dev.c:do_open() only calls bdev_set_size on the first open.
Picture two procs:
proc1: mount -o loop file1 mnt1
proc2: mount -o loop file2 mnt2
proc1 proc2
open /dev/loop0 # bd_openers now 1
do_open
bd_set_size(bdev, 0) # loop unbound, so bdev size is 0
open /dev/loop0 # bd_openers now 2
loop_set_fd # disk capacity now correct, but
# bdev not updated
mount /dev/loop0 /mnt
do_open
Because bd_openers != 0 for the last do_open, bd_set_size is not called
again and a size of 0 is used. This eventually leads to an oops when the
loop device is unmounted, because fsync_bdev calls block_write_full_page
who decides every page on the block device is outside i_size and unmaps
them.
When ext2 or reiserfs try to sync a metadata buffer, we get an oops on
because the buffers are no longer mapped.
The patch below changes loop_set_fd and loop_clr_fd to also manipulate the
size of the block device, which fixes things for me.

[PATCH] kbuild: fix usage with directories containing '.o'
From: Sam Ravnborg <sam@ravnborg.org>
From: Daniel Mack <daniel@zonque.org>, me
modpost unconditionally searched for ".o" assuming this is always the
suffix of the module. This fails in two cases:
a) when building external modules where any directory include ".o" in
the name. One example is a directory named: .../cvs.alsa.org/...
b) when someone names a kernel directory so it contains ".o". One
example is drivers/scsi/aic.ok/...
case b) was triggered by renaming the directory for aic7xxx, and modifying
Makefile and Kconfig. This caused make modules to fail.

[PATCH] Remove unneeded unlock in ipc/sem.c
From: Manfred Spraul <manfred@colorfullife.com>

sem_revalidate and then sem_unlock, even if sem_revalidate failed. The
sem_unlock call must be removed.

limit later, in a half-year or year or so.

[PATCH] Fix reading the last block on a bdev
From: Chris Mason <mason@suse.com>
This patch fixes a problem we're hitting on ia64 with page sizes > 4k.
When the page size is greater than the block size, and parts of the page
fall past the end of the device, readpage will fail because
blkdev_get_block returns -EIO for blocks past i_size.
The attached patch changes blkdev_get_block to return holes when reading
past the end of the device, which allows us to read that last valid 4k
block and then fill the rest of the page with zeros. Writes will still
fail with -EIO.

[PATCH] EDD: Get Legacy Parameters
From: Matt Domsch <Matt_Domsch@dell.com>
Patch below from Patrick J. LoPresti and myself. Patrick describes:
Why this patch? The problem is that the legacy BIOS interface
(INT13/AH=3D08) for querying the disk geometry returns different values
than the extended INT13 interface which the EDD code currently uses. This
is because the legacy interface only provides a 10-bit cylinder field, so
modern BIOSes "lie" about the head/sector counts in order to make more of
the disk visible within the first 1024 cylinders.
Many non-Linux applications, including the stock Windows boot loader, DOS
fdisk, etc., rely upon the legacy interface and geometry. So it is useful
to be able to obtain the legacy values from a running Linux kernel.
What this patch does is to add new entries under
/sys/firmware/edd/int13_devXX named "legacy_cylinders", "legacy_heads", and
"legacy_sectors". These provide the geometry given by the legacy
INT13/AH=3D08 BIOS interface, just like the current "default_cylinders"
etc. provide the the geometry given by the INT13/AH=3D48 interface.
Without this patch, I cannot use Linux to partition a drive and install
Windows, which happens to be my application.
- Pat
http://unattended.sourceforge.net/
In addition, this adds two buggy BIOS workarounds in the EDD int13
calls as suggested by Ralf Brown's interrupt list.
I'm also interested in moving this code out of arch/i386/kernel/edd.c and
include/asm-i386/edd.h, as I believe it is applicable on x86-64 as well.
However, there's no good place under drivers/ to put edd.c when it's not
tied to a bus, but to several CPU architectures and their firmwares...
Maybe a new directory drivers/firmware?

size IO. Doing at least 2 chunks is more than appropriate so that each
spindle will get a chance to merge IO's.

Various fixes and enhancements to the monitor hardware detection code. The

Old EDID parsing code was very verbose, half of the patch address this (ie.

stuff: we really need a way to know the origin of a video mode. In this way
we can select video mode that comes from EDID instead of VESA or GTF.
Drivers other than radeonfb won't be affected because they cannot (yet) get
EDID from the monitor and don't use EDID related code.

[PATCH] kswapd throttling fixes
The logic in balance_pgdat() is all bollixed up.
- the incoming arg `nr_pages' should be used to determine if we're being
asked to free a specific number of pages, not `to_free'.
- local variable `to_free' is not appropriate for the determination of
whether we failed to bring all zones to appropriate free pages levels.
Fix this by correctly calculating `all_zones_ok' and then use
all_zones_ok to determine whether we need to throttle kswapd.
So the logic now is:
for (increasing priority) {
all_zones_ok = 1;
for (all zones) {
to_reclaim = number of pages to try to reclaim

[PATCH] vmscan: preserve page referenced info in refill_inactive()
From: Nick Piggin <piggin@cyberone.com.au>
If refill_inactive_zone() is running in its dont-reclaim-mapped-memory mode

[PATCH] vm: scan slab in response to highmem scanning
The patch which went in six months or so back which said "only reclaim slab
if we're scanning lowmem pagecache" was wrong. I must have been asleep at
the time.
We do need to scan slab in response to highmem page reclaim as well. Because
all the math is based around the total amount of memory in the machine, and
we know that if we're performing highmem page reclaim then the lower zones
have no free memory.
<akpm@osdl.org>
[PATCH] vmscan: zone balancing fix
We currently have a problem with the balancing of reclaim between zones: much
more reclaim happens against highmem than against lowmem.
This patch partially fixes this by changing the direct reclaim path so it
does not bale out of the zone walk after having reclaimed sufficient pages
from highmem: go on to reclaim from lowmem regardless of how many pages we
reclaimed from lowmem.
<akpm@osdl.org>
[PATCH] vmscan: drive everything via nr_to_scan
Page reclaim is currently a bit schitzo: sometimes we say "go and scan this
many pages and tell me how many pages were freed" and at other times we say
"go and scan this many pages, but stop if you freed this many".
It makes the logic harder to control and to understand. This patch coverts
everything into the "go and scan this many pages and tell me how many pages
were freed" model.
It doesn't seem to affect performance much either way.
<akpm@osdl.org>
[PATCH] Balance inter-zone scan rates
When page reclaim is working out how many pages to san in a zone (max-scan)
it presently rounds that number up if it looks too small - for work batching.
Problem is, this can result in excessive scanning against small zones which
have few inactive pages. So remove it.
Not that it is possible for max_scan to be zero. That's OK - it'll become
non-zero as the priority increases.
<akpm@osdl.org>
[PATCH] vmscan: avoid bogus throttling
- If max_scan evaluates to zero due to a very small inactive list and high
`priority' numbers, we don't want to thrlttle yet.
- In balance_pgdat(), we may end up not scanning any pages because all
zones happened to be above pages_high. Avoid throttling in this case too.
<akpm@osdl.org>
[PATCH] kswapd: avoid unnecessary reclaiming from higher zones
Currently kswapd walks across all zones in dma->normal->highmem order,
performing proportional scanning until all zones are OK. This means that
pressure against ZONE_NORMAL causes unnecessary reclaim of ZONE_HIGHMEM.
To fix that up we change kswapd so that it walks the zones in the
high->normal->dma direction, skipping zones which are OK. Once it encounters
a zone which needs some reclaim kswapd will perform proportional scanning
against that zone as well as all the succeeding lower zones.
We scan the lower zones even if they have sufficient free pages. This is
because
a) the lower zone may be above pages_high, but because of the incremental
min, the lower zone may still not be eligible for allocations. That's bad
because cache in that lower zone will then not be scanned at the correct
rate.
b) pages in this lower zone are usable for allocations against the higher
zone. So we do want to san all the relevant zones at an equal rate.
<akpm@osdl.org>
[PATCH] kswapd: fix lumpy page reclaim
As kswapd is now scanning zones in the highmem->normal->dma direction it can
get into competition with the page allocator: kswapd keep on trying to free
pages from highmem, then kswapd moves onto lowmem. By the time kswapd has
done proportional scanning in lowmem, someone has come in and allocated a few
pages from highmem. So kswapd goes back and frees some highmem, then some
lowmem again. But nobody has allocated any lowmem yet. So we keep on and on
scanning lowmem in response to highmem page allocations.
With a simple `dd' on a 1G box we get:

[PATCH] fix the kswapd zone scanning algorithm
This removes a vestige of the old algorithm. We don't want to skip zones if
all_zones_ok is true: we've already precalculated which zones need scanning
and this just stops us from ever performing kswapd reclaim from the DMA zone.
<akpm@osdl.org>
[PATCH] vmscan: less throttling of page allocators and kswapd
This is just a random unsubstantiated tuning tweak: don't immediately
throttle page allocators and kwapd when the going is getting heavier: scan a
bit more of the LRU before throttling.
<akpm@osdl.org>
[PATCH] vmscan: batch up inactive list scanning work
From: Nick Piggin <piggin@cyberone.com.au>
Use a "refill_counter" for inactive list scanning, similar to the one used
for active list scanning. This batches up scanning now that we precisely
balance ratios, and don't round up the amount to be done.
No observed benefits, but I imagine it would lower the acquisition
frequency of the lru locks in some cases, and make codepaths more efficient
in general due to cache niceness.
<akpm@osdl.org>
[PATCH] fix vm-batch-inactive-scanning.patch
- prevent nr_scan_inactive from going negative
- compare `count' with SWAP_CLUSTER_MAX, not `max_scan'
- Use ">= SWAP_CLUSTER_MAX", not "> SWAP_CLUSTER_MAX".
<akpm@osdl.org>
[PATCH] vm: balance inactive zone refill rates
The current refill logic in refill_inactive_zone() takes an arbitrarily large
number of pages and chops it down to SWAP_CLUSTER_MAX*4, regardless of the
size of the zone.
This has the effect of reducing the amount of refilling of large zones
proportionately much more than of small zones.
We made this change in may 2003 and I'm damned if I remember why. let's put
it back so we don't truncate the refill count and see what happens.

[PATCH] add device quiescing to the SCSI API
This patch adds the ability to quiesce a SCSI device. The idea is that
user issued commands (including filesystem ones) would get blocked,
while mid-layer and device issued ones would be allowed to proceed.
This is for things like Domain Validation which like to operate on an
otherwise quiet device.
There is one big change: to get all of this to happen correctly,
scsi_do_req() has to queue on the *head* of the request queue, not the
tail as it was doing previously. The reason is that deferred requests
block the queue, so anything needing executing after a deferred request
has to go in front of it. I don't think there are any untoward
consequences of this.

[PATCH] more SPI transport attribute updates
This does three things
- Fix the signedness of the bit attributes (otherwise they show up as -1

- Add a visibility field to attributes, so drivers can get rid of
attributes they're never going to care about

[PATCH] update the 53c700 use of transport attributes
This patch just brings it up to date with the previous transport
attribute patch, moving it to the model where it sets the min/max of the

period and offset visible (it doesn't care about any of the others).

[PATCH] cdev 1/2: Eliminate /sys/cdev
This is the first of two patches designed to make life easier for authors
of device driver books - and, with luck, driver authors too.
/sys/cdev is, according to Al, a mistake which was never really meant to
exist. I believe nothing uses it currently - there isn't a whole lot there
to use. Its existence takes up system resources, and also requires drivers
to deal with the cdev's embedded kobject in their failure paths. The
following patch (against 2.6.4) makes it all go away.
OK, almost all. We have to keep (but not register) cdev_subsys because
it's rwsem is needed to control access to cdev_map.
<corbet@lwn.net>
[PATCH] cdev 2/2: hide cdev->kobj
The existing cdev interface requires users to deal with the embedded
kobject in two places:
- The kobject name field must be set before adding the cdev, and
- Should cdev_add() fail, a call to kobject_put() is required.
IMO, this exposure of the embedded kobject makes the interface more brittle
and harder to understand. It's also unnecessary. With the removal of
/sys/cdev, a call to cdev_del() will nicely replace kobject_put(), and the
name setting is easily wrapped.
This is against 2.6.4, but depends on the /sys/cdev removal patch.
<greg@kroah.com>
remove cdev_set_name completely as it is not needed.

[ACPI] ACPICA 20040311 from Bob Moore
Fixed a problem where errors occurring during the parse phase of control
method execution did not abort cleanly. For example, objects created
and installed in the namespace were not deleted. This caused all
subsequent invocations of the method to return the AE_ALREADY_EXISTS
exception.
Implemented a mechanism to force a control method to "Serialized"
execution if the method attempts to create namespace objects.
(The root of the AE_ALREADY_EXISTS problem.)
Implemented support for the predefined _OSI "internal" control method.
Initial supported strings are "Linux", "Windows 2000", "Windows 2001",
and "Windows 2001.1", and can be easily upgraded for new strings as
necessary. This feature allows Linux to execute
the fully tested, "Windows" code path through the ASL code
Global Lock Support: Now allows multiple acquires and releases with any
internal thread. Removed concept of "owning thread" for this special
mutex.
Fixed two functions that were inappropriately declaring large objects on
the CPU stack: ps_parse_loop() and ns_evaluate_relative().
Reduces the stack usage during method execution considerably.
Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the
S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.
Fixed a problem where acpi_ev_gpe_detect() would fault
if there were no GPEs defined on the machine.
Implemented two runtime options: One to force all control method
execution to "Serialized" to mimic Windows behavior, another to disable
_OSI support if it causes problems on a given machine.

[PATCH] Add Domain Validation to the SPI transport class
Domain Validation is a fairly essential element to the SCSI Parallel
Interface (although if you look very few drivers actually do it). The
premise is that the Parallel Bus, being a transmission line, might not
be correctly tuned to the transfers you want do perform. DV probes the
parameters of the transport until it finds a setting that works (for the
interested, see http://www.t10.org/ftp/t10/drafts/sdv/sdv-r08b.pdf)
The current code employs rather simplistic DV heuristics, although those
can be improved over time. The change in scsi_scan.c is so that DV may
be done easily from the slave_configure routine, which is the most
natural place to begin.

[PATCH] Fix removable USB drive oops
The actual problem reported was because there wasn't a corresponding
check on transport_classdev.class in the unregister.
However, on closer inspection I also turned up a nasty thinko in the
reference counting. For reasons best known to the class code authors,
class devices have to obtain their own references to the devices they're
attached to which they release again in their .release routines, so you
have to remember to do a get_device() in the correct place after the
class_device_add(). I put comments in the code so that, hopefully, we
can avoid the problem in future.

[WATCHDOG] v2.6.4 pcwd_pci-v1.00_20040313-patch
Two small fixes:
* Make cards_found a global variable so that if we remove the
pci device we can count down.
* If we can't find a correct I/O address for the card, then we
should disable the card again.
<wim@iguana.be>
WATCHDOG] v2.6.4 wdt977-v0.03-patch
Version 0.03 of wdt977.c - Changes that were made are:
* Extract the stop code in a seperate function (wdt977_stop)
* Extract the start code in a seperate function (wdt977_start)
* Rename kick_wdog to wdt977_keepalive for consistency
* Extract the watchdog's status code to a seperate function (wdt977_get_status)
* Change the way we deal with the watchdog timeout:
Up till now we used timeoutM (in minutes) as the correct value and then
calculated timeout as being timeoutM*60 or *timeoutM*120 (depending on
wether or not we have the netwinder hardware bug).
From now on timeout is the correct value and we calculate timeoutM out
of it. Because of this we start with checking wether or not we have a
correct timeout value (if not we reset it to the default value) and we
automatically calculate timeoutM. Each time we change timeout with a
correct timeout value, we recalculate timeoutM.
* Extended ioctl code with WDIOC_SETOPTIONS and updated the watchdog_info structure
* Added notifier support
Code has been tested by Woody

<trond.myklebust@fys.uio.no>
NFSv2/v3/v4: New attribute revalidation code that no
longer relies on ctime for correctness in avoiding
update races.
VFS: allow filesystems to disable inode_update_time() on
a per-inode basis.
<trond.myklebust@fys.uio.no>
NFSv2/v3/v4: New file writeout strategy. Defer writes until a flush
is requested by the application (or memory pressure).
<trond.myklebust@fys.uio.no>

NFSv2/v3: Ensure that we only use GETATTR+STATFS (NFSv2) and FSINFO (NFSv3) when
mounting. This should allow us to use AUTH_SYS credentials when mounting,
(even when the user requests RPCSEC_GSS authentication) due to the hack
described in RFC2623.
Remove the broken NFS_INO_FAKE_ROOT hack.
<trond.myklebust@fys.uio.no>
NFSv2/v3/v4: Ensure that fsync() flushes all writebacks to disk rather than just the
ones labelled as belonging to our file. This fixes a bug in which msync(MS_SYNC)
will fail to flush the pages to disk.
<trond.myklebust@fys.uio.no>

RPC: When trying to reconnect to a TCP port, try to bind() to the last used port number
in order to ensure that the servers NFS replay cache recognizes this as being the
same mount as before.
<trond.myklebust@fys.uio.no>
RPC,NFSv2/v3/v4: Ensure that xprt_create_proto() and rpc_create_client() return
full error codes. Should allow the "mount" program to print more useful error
diagnostics.

NFSv2/v3/v4: Parenthesize #defines in nfs?xdr.c. Fix an off-by-one error on the value
of compound_decode_hdr_maxsz.
NFSv4: fix a printk() typo (spotted by Linda Dunaphant).
NFSv4: Ensure that nfs4_open_reclaim() copies the value of the new stateid back into
the shared nfsv4 state structure.
NFSv4: Don't leak NFS4ERR_WRONGSEC errors back into nfs_lookup().
RPC,NFS,Lockd: Mark the debugging code as "unlikely" so that gcc moves it out of the
mainline code paths.
<trond.myklebust@fys.uio.no>
NFSv2/v3 locking: Patch by Patrice Dumas to implement nlmsvc_proc_granted_res.
When a server receives that callback it should deallocate the corresponding blocked

NFSv2/v3 locking: A patch to ensure that blocks which are not going to time out
are placed last on the ordered list nlm_block (problem reported by Olaf
Kirch).
<trond.myklebust@fys.uio.no>
RPC,NFSv3: remove the redundant "memset()" in call_encode(). Fix up the only places
where this causes a padding error: xdr_encode_fhandle() and unx_marshal()
<trond.myklebust@fys.uio.no>
RPC: patch by Chuck Lever to make the number of RPC slots a tunable parameter.
This is wanted in order to allow the NFS client to send more requests before
is has to block and wait for replies.
This is mainly useful if you have a WAN and want to ensure that the bandwidth
is being used efficiently.

<trond.myklebust@fys.uio.no>
NFS: From the suse kenrel RPM: handle ENOMEM from nfs_fhget().
<trond.myklebust@fys.uio.no>
From: <martin@meltin.net>
Forward-port from 2.4:
The following patch pulls an NFS server IP address off root_server_path
(handed out via the DHCP root-path option), if it is present. For example,
you can do this sort of thing in dhcpd.conf:
root-path = 192.168.1.33:/tftpboot/yip.zImage
This lets you mount your root filesystem off a different machine than you
booted from, without needing to use kernel command-line parameters.
The patch appears to be backwards compatible.
RFC2132 says this about the root-path option:
This option specifies the path-name that contains the client's root
disk. The path is formatted as a character string consisting of
characters from the NVT ASCII character set.
This is sufficiently vague to allow the path-name to include an IP-address.
Also, I found some documentation for FreeBSD saying it does this too, so it
must be right, because those FreeBSD guys are really smart... :-)
The only downside of the patch is that the summary that ipconfig prints can
be a little odd when the kernel command line overrides whatever ipconfig gets
from (say) DHCP. The address from the kernel command line seems to get
stripped off early, so ipconfig reports it, but it doesn't report the kernel
command line NFS path, since that's handled a bit later... This small
cosmetic problem looks difficult to "fix" without rewriting quite a bit of
stuff...
<trond.myklebust@fys.uio.no>

[PATCH] Manfred's patch to distribute boot allocations across nodes
From: Anton Blanchard <anton@samba.org>
Distribute boot time memory allocations across all nodes, from Manfred
Spraul.
We want to spread memory across nodes to avoid all allocations ending
up on node 0.
Spreading boot time allocations around also helps us to avoid node 0
becoming the hot node.
I took it for a spin:
buddyinfo before:
Node 7, 0 2 1 1 0 2 1 2 1 2 1 2 741

Node 0 107.35 MB
As you can see we gained over 100MB on node 0.

[PATCH] further __KERNEL_SYSCALLS__ removal
From: Arnd Bergmann <arnd@arndb.de>
Dave Jones already removed some of the useless __KERNEL_SYSCALLS__ defines
in various files, this gets rid of almost all the others. Replacing
execve() is nontrivial, so I left those in for now.
For all the other system calls that are currently used from inside the
kernel, calling the sys_* function directly should always have an identical
effect.
<akpm@osdl.org>
[PATCH] use wait_task_inactive() in kthread_bind()
From: Rusty Russell <rusty@rustcorp.com.au>
Make it clear that the reason we do wait_task_inactive is because
kthread_bind frobs with k->thread_info->cpu, which is only legal because
the task is definitely not running.
We can't use the normal migration thread code here, because it doesn't let
us bind to cpus which are offline yet, and also because we use this to
start the migration threads themselves.
<akpm@osdl.org>
[PATCH] md: use "shedule_timeout()" instead of yield()
From: NeilBrown <neilb@cse.unsw.edu.au>
Use "shedule_timeout()" instead of yield() as it seems to wait for less

<akpm@osdl.org>
[PATCH] md: allow assembling of partitioned arrays at boot time.
From: NeilBrown <neilb@cse.unsw.edu.au>
kernel parameters:

[PATCH] Work around an AMD768MPX erratum
From: Andi Kleen <ak@suse.de>
This patch has been in the SuSE 2.4 kernel forever, but for some reason
never made it mainline.
It works around the infamous "only works stable when a mouse is plugged in"
problem some AMD 768MPX Dual Athlon chipsets have. The problem happens
because the chipset can hang when PCI prefetch strides from a RAM page into
the VGA text buffer. When a PS2 mouse is plugged in the BIOS reserves a
page before the VGA text buffer, which stops the prefetch early.
This patch always reserves this page when the chipset could be AMD768MPX.
This can be only done early in bootmem setup. Because it's difficult to
scan the PCI bus that early it just always reserves this page when the CPU
is an Athlon. Normally it should not make a difference because the BIOS
will have reserved that page anyways when a PS/2 mouse is plugged in.

[PATCH] Add Domain Validation to 53c700 driver
This simply throws out the 53c700 driver's optimistic setting of the
best possible transport parameters and replaces it with DV
determination. It also adds a missing report_bus_reset() callback and
finally does a delayed DV on device errors.
<akpm@osdl.org>
[PATCH] DMA: Fill gaping hole in DMA API interfaces.
From: "David S. Miller" <davem@redhat.com>
Currently, for an existing DMA mapping, there is a way to transfer buffer
ownership back to the cpu, yet there is no way to give it back to the device
again explicitly. The latter really is needed on platforms where the PCI
subsystem does not snoop the cpu caches, MIPS is one example.
Many drivers were expecting the existing DMA sync interface to handle both
directions, which was wrong.
Now, with this change, we have explicit interfaces for DMA syncing to/from
the device and the cpu.
<akpm@osdl.org>
[PATCH] module unload deadlock fix
From: Rusty Russell <rusty@rustcorp.com.au>
From: Andrea Arcangeli <andrea@suse.de>
We should drop module sem before calling mod->exit, for practical reasons:
too many module exit functions oops or hang, resulting in a permenantly held
module sem, which blocks all module ops including lsmod.

[PCMCIA] Add, fix, update PCMCIA debugging.
The PCMCIA core debugging assumes that "pc_debug" is a global. If
pc_debug were to be a global, it would pollute the kernel's global
name space, potentially clashing with PCMCIA drivers and even ds.c.
We also get rid of PCMCIA using the "DEBUG" macro, which is the
standard macro to enable debugging in the kernel. Instead, we
introduce cs_dbg() for core PCMCIA debugging, ds_dbg() for driver
services debugging, and similar macros in the socket drivers.

<rmk@flint.arm.linux.org.uk>
[PCMCIA] socket user operations should take pcmcia_socket
Patch from Dominik Brodowski, updated by Russell King.
The pcmcia_{suspend,resume,eject,insert}_card calls are only issued

caller (ds) has a valid "handle", as long as it knows the proper
struct pcmcia_socket.
<akpm@osdl.org>
[PATCH] move consistent_dma_mask to the generic device
From: James Bottomley <James.Bottomley@SteelEye.com>
pci_dev.consistent_dma_mask was introduced to get around problems in the
IA64 Altix machine.
Now, we have a use for it in x86: the aacraid needs coherent memory in a
31 bit address range (2GB). Unfortunately, x86 is converted to the dma
model, so it can't see the pci_dev by the time coherent memory is
allocated.
The solution to all of this is to move pci_dev.consistent_dma_mask to
dev.coherent_dma_mask and make x86 use it in the dma_alloc_coherent()
calls.
This should allow me to make the aacraid set the coherent mask instead
of using it's current dma_mask juggling.

[SPARC32]: Rework the CPU enumeration and probing code
The low 2 bits of the MID are now used exclusively as the software
CPU ID on 4m. This eliminates entirely the need for mid_xlate. We
also eliminate linux_num_cpus and linux_cpus; since the hardware-based
id is now used everywhere we don't need indexed CPU tables.
The device probe is almost identical to sparc64's version. The one
exception is that 4m only uses the bottom 2 bits of the MID, so we also
have a separate function to get the true hardware MID for the rare times
it's actually needed.
Per-cpu data is now used the same way as in sparc64. As a side benefit
we now display the same format Bogo and Clock values in /proc/cpuinfo.
<wesolows@foobazco.org>
[SPARC32]: Also remove num_cpus_possible as was done on sparc64

[libata sata_sil] remove incorrect limit on drive quirk
The original submittor of the quirk code noted that the errata
of a lockup creating when the condition "sector % 15 == 1" is
true only on chip revisions <= 1. This is limitation on chip
revision is apparently not correct, therefore we apply to all
affected drives in the quirk list.
This is a sledgehammer fix, limiting max-sectors to 15. A much better
fix would split the hardware request into two taskfiles, issuing
an additional command, thereby avoiding "sectors % 15 == 1"
Given the errata is limited to "sil 311x + <these drives>", it is hoped
that some janitor cares enough to do a real fix.

Remove unused ide_task_t->posthandler and all ide_cmd_type_parser() logic.
ide_cmd_type_parser() was meant to be used for ioctls but
ended up checking validity of kernel generated requests (doh!).
Rationale for removal:
- it can't be used for existing ioctls (changes the way they work)
- kernel shouldn't check validity of (root only) user-space requests
(it can and should be done in user-space)
- it wastes CPU cycles on going through parsers
- it makes code harder to understand/follow

[libata] disable clustering by default, whitespace cleanups
Disable SCSI's clustering of S/G entries, typically reducing overall
S/G list size. Although ATA S/G tables are getting smarter (64-bit
address, 32-bit length, no DMA boundary besides 4G itself), working
harder to generate large byte sizes for each S/G size is not necessarily
in our best interest:
* SATA consists of frames, much like ethernet, called "FIS". A
Data FIS consists of up to 2048 dwords (8K) of data. We don't want
generate large byte sizes in S/G entries, just to have the host controller
break them up again into smaller chunks.
* Reduces the possibility that ata_fill_sg (libata-core.c) must split
an S/G into two pieces, because it straddles a 64K boundary.

[PATCH] I2C: fix forced i2c chip drivers have no name
I just noticed that I am doing something wrong in the i2c chip drivers I
ported to Linux 2.6. If these drivers are forced to a specific chip type
("kind" as we call it internally), then the device doesn't have its name
set (and defaults to an empty string).
Affected drivers: gl518sm, lm83, lm90, w83l785ts.
I could verify the problem on my ADM1032 chip (lm90 driver). I also
verified that the proposed patch fixes the issue.
You may notice that I fix the problem differently for gl518sm and
w83l785ts on the one hand, and lm83 and lm90 on the other hand. This is
because the first two drivers are not expected to support more a single
chip in the future, while lm90 already does and lm83 could someday (for
example, support for the LM82 could be added on request).
<khali@linux-fr.org>
[PATCH] I2C: Don't handle kind errors that cannot happen
A number of chip drivers in 2.6.4-mm1 try to handle an error case that
cannot happen when setting the chip name. The following patch changes
that.
Affected drivers: adm1021, it87, lm75, lm78, lm85, w83627hf, w83781d.
Note that in any case, the worst that could happen (but then again, it
cannot happen) is that the chip name would be set to an empty string,
which doesn't hurt much.
The patch also cleans up a few things in it87, w83627hf and w83781d,
which are tightly related to the rest of the changes and necessary for
them to be safe.
it87: There is only really one "kind" in this driver, so I removed all
references to other kinds.
w83627hf: The driver did not handle unknown chips.
w83781d: The user shouldn't be allowed to force a kind that doesn't
match the chip's bus type (I2C or ISA). The code was not meant to handle
that case, although no check was done so far.
Tested on my AS99127F, works as intended.
<khali@linux-fr.org>
[PATCH] I2C: Setting w83781d fan_div preserves fan_min
This patch makes the w83781d driver preserve fan_min settings when the
user changes fan_divs. This isn't done "by default" because the actual
fan min value (in RPMs) depends on both the fan_min register and the
fan_div register. Only two drivers handle it properly at the moment as
far as I know (lm78 and asb100). Several other drivers would need to be
fixed the same way, but well, once at a time ;)
Tested on my AS99127F rev.1.
Credits go to Philip Pokorny, since I think I remember he is the one who
introduced the method in the lm78 driver in the first place.
This tends to increase the size of the three set_store_regs_fan_div
functions, and I am considering refactoring them at some point. Later
though.

Anyway, the problem that this fixes is that megaraid doesn't set the
moduler owner for the host_template, this means that the module can be
removed, even when it is in use.

[PATCH] g5: Fix iommu vs. pci_device_to_OF_node
The g5 iommu code would fill the "iommu_table" member of whatever
device node was pointed to by pcidev->sysdata during boot. However,
the ppc64 kernel fills that with a pointer to the PHB node which is
later replaced "lazily" with a pointer to the real node when calling
pci_device_to_OF_node(). In this case, we were thus "losign" the
iommu_table pointer. Typical symptom: loss of the SATA when looking
at it's /proc entry.
This fixes it by forcing the update to the final sysdata pointer
when filling up the iommu_table pointers. The "lazy" thing is useless
on pmac anyway.

[PATCH] Fix early parallel make failures
From: Sam Ravnborg <sam@ravnborg.org>
Ingo said:
Starting at around 2.6.4-rc2-mm1, I keep seeing 'scripts/fixdep: Text
file busy' messages when doing a -j10 bzImage build - which seems to
suggest that by the time fixdep is used by the build system it's not
built yet.
Sam said:
I was pretty sure it was something I had caused, so I gave it a spin. What
actually happened was that we tried to build the target 'silentoldconfig'
in parrallel with 'scripts'. Since 'silentoldconfig' started a new make
and then the config target needed 'scripts' we saw two parallel runs.
The way I decided to fix it was to split scripts/ in two parts. The first
part is now the very basic stuff - moved to scripts/basic/. The second
part is dependent on kernel config etc. and kept in scripts/
In the 2.7 timeframe i will redo this initial stuff - it's becoming too
messy for anyone to understand today.
Description:
Fix dependencies in early phases of kernel build. This solves a few
problems nively: modpost is no longer rebuild twicewhen reaching the
'target' state 'make -j10' now works nicely again
The patch is rather large due to the following file moves:
mkdir scripts/basic
mv scripts/fixdep.c scripts/basic
mv scripts/split-include.c scripts/basic
mv scripts/docproc.c scripts/basic

[PATCH] selinux: Conditional policy extension and MLS detection support
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch extends the SELinux policy engine to support conditional policy
logic based on a set of policy booleans, allowing well-formed changes to
the policy to be defined within and mediated by the policy itself.
The conditional policy extensions were implemented and contributed by
Tresys Technology.
Userland packages that support these extensions are already available from
nsa.gov/selinux, and backward compatibility is provided for the prior
policy version.
The patch also includes a small change to enable detection of the optional
MLS policy model on a SELinux system and fixes to the conditional policy
extensions to allow the MLS policy to work correctly with them that were
implemented and contributed by Trusted Computer Solutions.

[PATCH] ide-scsi error handling fixes
From: Willem Riede <wrlk@riede.org>
The patch revises the error handling in ide-scsi, fixing the scheduling
while locked issues, and make it work properly, at least for me...
Specific changes in this patch:
- introduce idescsi_expiry, a timeout routine for the ide subsystem,
which simply flags the fact that the command timed out, but postpones
any other action until either the command still finishes on its own
(unlikely?) or the scsi error handler kicks in;
- introduce idescsi_atapi_error and idescsi_atapi_abort, error routines
for the ide subsystem, which are modeled after those of ide-cd, but
take only minimal effort to recover, leaving the heavy lifting for
the scsi error handler;
- rewrite (and rename for clarity) idescsi_eh_abort and idescsi_eh_error,
the abort/error routines to be called by the scsi error handler --
this redesign should not have the scheduling while atomic problems
of the old implementation.
- move ide_cdrom_dump_status() from ide-cd.c to ide-lib.c as
ide_dump_atapi_status() and both ide-cd and ide-scsi call it.
- replaces BUG() by WARN_ON()/printk in the error handling code.
- sets TASK_UNINTERRUPTIBLE before schedule_timeout() and moves the host
unlock/lock around the while loop inside the loop in idescsi_eh_reset().

From: Sam Ravnborg <sam@ravnborg.org>
modpost or to be more specific sumversion.c was not behaving correct when

local .h when calculation the md-sum in case of a O= build.
The following patch introduces the following:
- A generic get_next_line()
- Check that the topmost part of the directory matches
- Using strrch when checking for file with suffix .o
- Use NOFAIL for allocations in sumversion
- Avoid memory leak in new_module
The generic get_next_line will pay off when Andreas implmentation of
storing symbol addresses in a seperate file is introduced.

[PATCH] flush_scheduled_work() deadlock fix
Because keventd is a resource which is shared between unrelated parts of the
kernel it is possible for one person's workqueue handler to accidentally call
another person's flush_scheduled_work(). thockin managed it by calling
mntput() from a workqueue handler. It deadlocks.
It's simple enough to fix: teach flush_scheduled_work() to go direct when it
discovers that the calling thread is the one which should be running the
work.
Note that this can cause recursion. The depth of that recursion is equal to
the number of currently-queued works which themselves want to call
flush_scheduled_work(). If this ever exceeds three I'll eat my hat.

From: BlaisorBlade <blaisorblade_spam@yahoo.it>, and me
- remove unused `file *' arg from do_write_mem()
- Add checking for copy_from_user() failures in do_write_mem()
- Return correct value from kmem writes() when a fault is encountered. A
write()-style syscall's return values are:
0 when nothing was written and there was no error (someone tried to
write zero bytes)
>0: the number of bytes copied, whether or not there was an error.
Userspace detects errors by noting that the write() return value is less
than was requested.
<0: there was an error and no bytes were copied

[PATCH] slab: fix display of object length in corruption detector
From: Manfred Spraul <manfred@colorfullife.com>
print_objinfo() dumps the first few characters of an interesting object for

of just the data area), which could cause an oops if DEBUG_PAGEALLOC is
enabled.

[PATCH] kill INIT_THREAD_SIZE
From: Matt Mackall <mpm@selenic.com>
This piece of the THREAD_SIZE cleanup got dropped. If you make THREAD_SIZE
> 8k, the init thread overlaps the .init section and gets smashed. I've
gone ahead and killed INIT_THREAD_SIZE throughout as it wasn't doing much.
This also saves 4k when we use 4k stacks. Please apply. Couple more minor
pieces remaining.

[PATCH] iostats averaging fix
From: Rick Lindsley <ricklind@us.ibm.com>
Fix bug #2230.
I've corresponded with the submitter and he did find a real bug -- when we
were merging I/O requests we didn't always take the oldest request start
time, which would cause a couple of the calculations like wait time and
average queue size to be too small. He found it mathematically but having
done so, I think logic and inspection makes it easy to verify.

[PATCH] Fix for hotplug of multifunction cards.
From: Linda Xie <lxiep@us.ibm.com>
The changes in this patch are for multifunction cards insertions/removals

2. new nodes' phb, devfn(and so on) need to be fixed even the nodes don't
have "interrupts".
3. change of_remove_node to non-recurisve func. The recursions will be done
by the caller.
4. add a new function -- of_finish_dynamic_node_interrupts()

[PATCH] Fix multiple EEH-related bugs
From: Linas Vepstas <linas@austin.ibm.com>
This patch fixes multiple EEH-related bugs:
- Fixes the eeh_check_failure() usage in an interrupt context.
This routine is now safe to use in an interrupt. The fix was to
build a cache of IO addresses and check that, instead of using
the pci routines.
- Merges in Olof Johansson's sizeof patch when checking for failure
- Adds EEH tests to array/string reads
- Fixes bugs with address resolution (some i/o addresses were handled
incorrectly, resulting in EEH errors slipping by undetected.)
- Adds EEH support to the PCI Hotplug system (so that devices that
get added/removed get properly registered with the EEH subsystem.)
- Fixes improper use of /proc filesystem.
- Adds some misc statistics.
While merging Linas' patch I also converted the proc usage to
seq_single, used per cpu variables for the stats and removed the
eeh-force-off option.
<akpm@osdl.org>
[PATCH] Fix xics IRQ affinity
From: Anton Blanchard <anton@samba.org>
- Merge some whitespace differences with the ameslab tree
- We check for CPU_MASK_ALL in xics to send irqs to all cpus.
In some cases CPU_MASK_ALL is smaller than the cpumask (eg
NR_CPUS == 32 and cpumask is a long), so we mask it here to
be consistent.

In xics_get_irq(), for a real-to-virt irq lookup, go down the

[PATCH] Cleanup ppc64 procfs code
From: Anton Blanchard <anton@samba.org>
Cleanup ppc64 procfs code:
- Use initcalls everywhere. This allowed us to remove the iseries proc
callback interface.
- Kill proc_pmc.c. Most of it wasnt used (and we are planning to export the
PMCs via sysfs). The few things left were iseries specific so they
got moved into iSeries_proc.c.
- Kill pmc.c. We dont use those statistics and the ones that are left
can be gained via PMCs.
- Create /proc/iSeries and /proc/ppc64 very early. This means we no
longer have to call proc_ppc64_init in all the drivers, we can
assume its there.
- Fix some error return cases in rtas-proc.c and rtas-flash
- Dont even try some pseries specific drivers on pmac.

[PATCH] wait_task_inactive should not return on preempt
wait_task_inactive is now only used in two non-time-critical places: the
ptrace code to guarantee a schedule and kthread_bind so we can change
the thread CPU. Unfortunately with preempt, the code as stands has a
race: we might return because the thread is preempted, not because it
actually reached schedule(). The ptrace code (probably) doesn't care,
but the kthread code does.
This patch simplifies the (now over-optimized) code, and does a yield()
for the preemption case.

[PATCH] ide-scsi.c: fix ATAPI multi-lun support
ATAPI multi-lun support has been broken for a long time.
It used to be that "(drive->id->last_id & 0x7) + 1" was used as
shost->max_lun and the "hdXlun=" kernel parameter could be used to
override this value.
However it was far from optimal:
- people played with "hdXlun=" and then complained about multiple instances
of the same device (most ATAPI drives respond to each LUN)
- probably some devices return 7 not 0 in id->last_id (=> 7 x same device)
This patch from Willem Riede <wrlk@riede.org> fixes it w/o need
for "hdXlun=" option. It was tested by Willem on ATAPI PD/CD drive.

[PATCH] x86 vsyscall alignment fix
From: Andy Whitcroft <andyw@uk.ibm.com>
The vsyscall implementation for ia32 provides two different vsyscall pages;
one to use int80 and the other to use sysenter. Each includes a common
signal trailer. The kernel requires the alignment of routines in this
trailer be consistent in both copies. However this is not enforced at
compile time. Failure to maintain this alignment typically leads to an
obscure SIGSEGV in init during boot. This critical alignment requirement
is not well documented.
Below is a patch to better document the alignment requirements and to
enforce the requirement.

From: "Kenneth Chen" <kenneth.w.chen@intel.com>

From: Arun Sharma <arun.sharma@intel.com>
The current Linux implementation of shmat() insists on SHMLBA alignment even

[netdrvr de2104x] fix ifup/down and promise mode
The attached patch fixes the problem: de->macmode variable,

2.4 kernel doesn't shadow this register at all, so I removed
shadowing from 2.6 as well.

ia64: Prevent GCC from clobbering r13. Found by Luming You.
Without this change, GCC thinks it's OK to clobber r13. It doesn't do it
very often, but it's enough if it does it once and it turns out
acpi_bus_receive_event() had code that would trigger this issue.
Fix by declaring r13 as a global register variable.

[PATCH] ia64: force all kernel sections into one and the same segment
Older versions of the linker do not handle cross-segment segment-relative
relocations properly. This becomes a real problem when the linker decides
to put .text and .text.init into different segments (for whatever reasons)
because in that case, broken linkers will produce a broken unwind section,
which can cause nasty Heisenbugs, where, for example, unwinding may or may
not work depending on the exact value of the IP in a function.

[PATCH] ppc32: Fix booting some IBM PRePs
From: Tom Rini <trini@kernel.crashing.org>
The following patch comes from Paul Mackerras. Earlier on in 2.6,
arch/ppc/boot/utils/mkprep.c was changed slightly so that it would build
and work on Solaris. Doing this required changing from filling out
pointers to an area to filling out a local copy of the struct. However, a
memcpy was left out, and the info is only needed on some machines to boot.
The following adds in the missing memcpy and allows for IBM PRePs to boot
from a raw floppy again.

[PATCH] exportfs - Remove unnecessary locking from find_exported_dentry()
From: "Jose R. Santos" <jrsantos@austin.ibm.com>
After discussing it with Neil, he fell that the original justification for
taking the kernel_lock on find_exported_dentry() is not longer valid and
should be safe to remove.
This patch fixes an issue while running SpecSFS where under memory
pressure, shrinking dcache cause find_exported_dentry() to allocate
disconnected dentries that later needed to be properly connected. The
connecting part of the code was done with BKL taken which cause a sharp
drop in performance during iterations and profiles showing 75% time spent
on find_exported_dentry(). After applying the patch, time spent on the
function is reduce to <1%.
I have tested this on an 8-way machine with 56 filesystems for several days
now with no problems using ext2, ext3, xfs and jfs.

[PATCH] hpfs: namei.c failure case cleanups
Failure exits in hpfs/namei.c merged and cleaned up.
<viro@www.linux.org.uk>
[PATCH] hpfs: clean up lock ordering
hpfs_{lock,unlock}_{2,3}inodes() killed; all places that take more than
one lock have ->i_sem held by VFS on all inodes involved and all hpfs per-inode
locks are of the same type. IOW, we can replace these guys with multiple
hpfs_lock_inode() - order doesn't matter here.
<viro@www.linux.org.uk>
[PATCH] hpfs: new/read/write_inode() cleanups
1) common initialization for all paths in hpfs_read_inode() taken into
a separate helper (hpfs_init_inode())
2) hpfs mkdir(),create(),mknod() and symlink() do not bother with
iget() anymore - they call new_inode(), do initializations and insert new
inode into icache. Handling of OOM failures cleaned up - if we can't
allocate in-core inode, bail instead of corrupting the filesystem.
Allocating in-core inode early also avoids one of the deadlocks here
(hpfs_write_inode() from memory pressure by kmem_cache_alloc() could
deadlock on attempt to lock our directory).
3) hpfs_write_inode() marks the inode dirty again in case if it
fails to iget() its parent directory. Again, OOM could trigger fs corruption
here.
<viro@www.linux.org.uk>
[PATCH] hpfs: hpfs iget locking cleanup preparation
Preparation to hpfs iget locking cleanup - remaining iget() callers
replaced with explicit iget_locked() + call hpfs_read_inode()/unlock_new_inode()
if inode is new.
<viro@www.linux.org.uk>
[PATCH] hpfs: hpfs iget locking cleanup
Killed the nightmares in hpfs iget handling. Since in some (fairly
frequent) cases hpfs_read_inode() could avoid any IO (basically, lookup
hitting a native HPFS regular file can get all data from directory
entry) hpfs had a flag passed to that sucker. Said flag had been
protected by a semaphore lookalike made out of spit and duct-tape and
callers of iget looked like
hpfs_lock_iget(sb, flag);
result = iget(sb, ino);
hpfs_unlock_iget(sb);
Since now we are calling hpfs_read_inode() directly (note that calling
it without hpfs_lock_iget() would simply break) we can forget all that
crap and get rid of the flag - caller knows what it wants to call.
BTW, that had killed one of the last sleep_on() users in fs/*/*.
<viro@www.linux.org.uk>
[PATCH] hpfs: deadlock fixes
We used to have GFP_KERNEL kmalloc() done by the code that held hpfs
lock on directory. That could trigger a call of hpfs_write_inode() and
deadlock; fixed by switch to GFP_NOFS. Same for hpfs inodes themselves
- hpfs_write_inode() calls iget() and that could trigger both the
deadlocks (avoidable with very baroque locking scheme) and stack
overflows (unavoidable unless we kill potential recursion here).
<viro@www.linux.org.uk>
[PATCH] hpfs: fix locking scheme
Fixed the locking scheme. The need of extra locking was caused by
the fact that hpfs_write_inode() must update directory entry; since HPFS
directories are implemented as b-trees, we must provide protection both
against rename() (to make sure that we update the entry in right directory)
and against rebalancing of the parent.
Old scheme had both deadlocks and races - to start with, we had no
protection against rename()/unlink()/rmdir(), since (a) locking parent
was done without any warranties that it will remain our parent and (b)
check that we still have a directory entry (== have positive nlink) was
done before we tried to lock the parent. Moreover, iget serialization
killed two steps ago gave immediate deadlocks if iget() of parent had
triggered another hpfs_write_inode().
New scheme introduces another per-inode semaphore (hpfs-only,
obviously) protecting the reference to parent. It's taken on
rename/rmdir/unlink victims and inode being moved by rename. Old semaphores
are taken only on parent(s) and only after we grab one(s) of the new kind.
hpfs_write_inode() gets the new semaphore on our inode, checks nlink and
if it's non-zero grabs parent and takes the old semaphore on it.
Order among the semaphores of the same kind is arbitrary - the only
function that might take more than one of the same kind is hpfs_rename()
and it's serialized by VFS.
We might get away with only one semaphore, but then the ordering
issues would bite us big way - we would have to make sure that child is
always locked before parent (hpfs_write_inode() leaves no other choice)
and while that's easy to do for almost all operations, rename() is a bitch -
as always. And per-superblock rwsem giving rename() vs. write_inode()
exclusion on hpfs would make the entire thing too baroque for my taste.
->readdir() takes no locks at all (protection against directory
modifications is provided by VFS exclusion), ditto for ->lookup().
->llseek() on directories switched to use of (VFS) ->i_sem, so
it's safe from directory modifications and ->readdir() is safe from it -
no hpfs locks are needed here.

[PATCH] ppc64: Fix SLB reload bug
From: Paul Mackerras <paulus@samba.org>
Recently we found a particularly nasty bug in the segment handling in the
ppc64 kernel. It would only happen rarely under heavy load, but when it
did the machine would lock up with the whole of memory filled with
exception stack frames.
The primary cause was that we were losing the translation for the kernel
stack from the SLB, but we still had it in the ERAT for a while longer.
Now, there is a critical region in various exception exit paths where we
have loaded the SRR0 and SRR1 registers from GPRs and we are loading those
GPRs and the stack pointer from the exception frame on the kernel stack.
If we lose the ERAT entry for the kernel stack in that region, we take an
SLB miss on the next access to the kernel stack. Taking the exception
overwrites the values we have put into SRR0 and SRR1, which means we lose
state. In fact we ended up repeating that last section of the exception
exit path, but using the user stack pointer this time. That caused another
exception (or if it didn't, we loaded a new value from the user stack and
then went around and tried to use that). And it spiralled downwards from
there.
The patch below fixes the primary problem by making sure that we really
never cast out the SLB entry for the kernel stack. It also improves
debuggability in case anything like this happens again by:
- In our exception exit paths, we now check whether the RI bit in the
SRR1 value is 0. We already set the RI bit to 0 before starting the
critical region, but we never checked it. Now, if we do ever get an
exception in one of the critical regions, we will detect it before
returning to the critical region, and instead we will print a nasty
message and oops.
- In the exception entry code, we now check that the kernel stack pointer
value we're about to use isn't a userspace address. If it is, we print a
nasty message and oops.
This has been tested on G5 and pSeries (both with and without hypervisor)
and compile-tested on iSeries.

[PATCH] sysfs_remove_dir-vs-dcache_readdir race fix
From: Maneesh Soni <maneesh@in.ibm.com>
I have re-done the patch fixing the race between sysfs_remove_dir() and
dcache_readdir(). If you recall, sysfs_remove_dir(kobj) manipulates the
->d_subdirs list for the dentry corresponding to the sysfs directory being
removed. It can end up deleting the cursor dentry which is added to the
->d_subdirs list during a concurrent dcache_dir_open() ==> dcache_readdir()
for the same directory. And as a result dcache_readdir() can loop for ever
holding dcache_lock.
The earlier patch which was included in -mm1 created problems which
resulted in list_del() BUG hits in prune_dcache(). The reason I think is
that in the main loop in sysfs_remove_dir(), dcache_lock is dropped and
re-acquired, and this could result in inconsistent ->d_subdirs list and
prune_dcache() may try to delete an already deleted dentry. I have
corrected this in the new patch as below.
I could do sysfs_remove_dir() more neatly on sysfs backing store patch set
as there I don't use the ->d_subdirs list. Instead the list of children
sysfs_dirent works out well. But untill sysfs backing store patch is
picked up the existing code suffer from this race. This can be easily
tested by running following two loops on a SMP box
# while true; do insmod drivers/net/dummy.ko; rmmod dummy; done
# while true; do find /sys/class/net > /dev/null; done
o This patch fixes sysfs_remove_dir race with dcache_readdir. There is
no need for sysfs_remove_dir to modify the d_subdirs list for the
directory being deleted as it is taken care in the final dput. Modifying
this list results in inconsistent d_subdirs list and causes infinite loop
in concurrently occurring dcache_readdir.
o The main loop is restarted every time, dcache_lock is re-acquired in
order to maintain consistency.

[PATCH] sysfs: pin kobjects to fix use-after-free crashes
From: Maneesh Soni <maneesh@in.ibm.com>
Fix a sysfs use-after-free crash. The problem we have is of the kobject
going away while we have a live dentry (the corresponding sysfs directory)
still pointing to it throuh d_fsdata pointer. The patch makes sure to keep
the kobject alive by taking a reference to it during the life-time of
corresponding dentry.
o The following pins the kobject when sysfs assigns dentry and inode to
the kobject. This ensures that kobject is alive during the life time of
the dentry and inode, and people holding ref. to the dentry can access the
kobject without any problems.
o The ref. taken for the kobject is released through dentry->d_op->d_iput()
call when the dentry ref. count drops to zero and it is being freed. For
this sysfs_dentry_operations is introduced.
For testing one has to run the following test on a SMP box:
1) Do insmod/rmmod "dummy.o" network driver in a forever loop.
2) Parallely do "find /sys/class/net | xargs cat" also in a forever loop.

[PATCH] kconfig: fix xconfig on /lib64 properly
From: Roman Zippel <zippel@linux-m68k.org>
The correct link path is needed at config time to find the correct library,
so let's ask gcc for the real path.
<akpm@osdl.org>
[PATCH] kconfig: don't rename target dir when saving config
From: Roman Zippel <zippel@linux-m68k.org>
conf_write() now checks the target path whether it's a directory, so it
saves the config in the directory instead of renaming it.
<akpm@osdl.org>
[PATCH] config: disable debug prints
From: Roman Zippel <zippel@linux-m68k.org>
This disables some debug prints, which are more confusing than helpful for
normal users.
<akpm@osdl.org>
[PATCH] config: persistent qconf configuration
From: Roman Zippel <zippel@linux-m68k.org>
This patch is by Andreas Fester <Andreas.Fester@gmx.de> and saves and
restores various runtime options of qconf.
<akpm@osdl.org>
[PATCH] config: choice fix
From: Roman Zippel <zippel@linux-m68k.org>
When a boolean choice value has a dependency of 'm' it can be shortly
treated as a tristate symbol. This fixes this and also add a small
optimization to precompute the value of the module symbol instead of
checking it all the time.
<akpm@osdl.org>
[PATCH] 8250_pnp: probe and remove can be __devinit/__devexit
From: "Randy.Dunlap" <rddunlap@osdl.org>
From: Luiz Fernando Capitulino <lcapitulino@prefeitura.sp.gov.br>

[PATCH] doc. updates/typos
From: "Randy.Dunlap" <rddunlap@osdl.org>
Remove the rest of references to smp.tex
Documentation/cpufreq => Documentation/cpu-freq
DocBook/tulip.{pdf,ps,html} => DocBook/tulip-user.{pdf,ps,html}
Bunch of other typos.

[PATCH] ip2: fix double operator
From: "Randy.Dunlap" <rddunlap@osdl.org>
This trivial patch fixes the bug #320:
http://bugme.osdl.org/show_bug.cgi?id=320
The additional comment:
http://bugme.osdl.org/show_bug.cgi?id=320#c1
Is wrong, because it will send the command twice.
We only want to see if the command got success, thus is not necessary
to test against < 0 (if the return value is not 1, we got a error).
Note that I'm using the function (bad) style.
<akpm@osdl.org>
[PATCH] procfs: use kernel min/max
From: "Randy.Dunlap" <rddunlap@osdl.org>
From: Michael Veeck <michael.veeck@gmx.net>
Patch (against 2.6.3) removes unnecessary min/max macros and changes calls to
use kernel.h macros instead.
<akpm@osdl.org>
[PATCH] reiserfs: use kernel min/max
From: "Randy.Dunlap" <rddunlap@osdl.org>
From: Michael Veeck <michael.veeck@gmx.net>
Remove unnecessary min/max macros and changes calls to use kernel.h macros
instead.
<akpm@osdl.org>
[PATCH] sound: use kernel min/max
From: "Randy.Dunlap" <rddunlap@osdl.org>
From: Michael Veeck <michael.veeck@gmx.net>
Remove unnecessary min/max macros and changes calls to use kernel.h macros
instead.
<akpm@osdl.org>
[PATCH] zlib: use kernel min/max
From: "Randy.Dunlap" <rddunlap@osdl.org>
From: Michael Veeck <michael.veeck@gmx.net>
Remove unnecessary min/max macros and changes calls to use kernel.h macros
instead.
<akpm@osdl.org>
[PATCH] fix HZ leaking to userspace in BSD accounting
From: Tim Schmielau <tim@physik3.uni-rostock.de>
BSD accounting was missed in the conversion from HZ to USER_HZ. I thought
nobody cared, but apparently there are still users to it.
<akpm@osdl.org>
[PATCH] Fix uninlined memcmp on i386
From: DHollenbeck <dick@softplc.com>
This patch was needed against a pristine 2.6.4 kernel when compiling with
"gcc 3.4 _very recent_" using the -Os option.
Without this patch, modules would use a non-inline memcmp() and then not
find it in the kernel, causing depmod to complain and some modules not to
load.
<akpm@osdl.org>
[PATCH] EDD: move code from i386-specific locations to generic
From: Matt Domsch <Matt_Domsch@dell.com>
Three patches to move the BIOS Enhanced Disk Drive code from i386-specific
locations into more generic locations, which will allow it to be used on
x86-64 as well.
move edd.h from include/asm-i386 to include/linux
<akpm@osdl.org>
[PATCH] EDD: move code from i386-specific locations to generic
From: Matt Domsch <Matt_Domsch@dell.com>
move edd.c from arch/i386/kernel to new dir drivers/firmware. Fix up
makefiles and Kconfigs.
<akpm@osdl.org>
[PATCH] EDD: split assembly code
From: Matt Domsch <Matt_Domsch@dell.com>
Split EDD assembly code from setup.S into edd.S. This will enable it to be
#included into x86-64 too.
<akpm@osdl.org>
[PATCH] pte_chain comment fix
From: Carl Spalletta <ioanamitu@yahoo.com>
Fix a comment bug.
<akpm@osdl.org>
[PATCH] add note about "Copyright" to SubmittingDrivers
From: Grant Grundler <grundler@parisc-linux.org>
This patch adds a comment to "Documentation/SubmittingDrivers" about the
importance of adding a Copyright notice in submitted code.
The parisc-linux port has neglected this in the past and I've been slowly
trying to correct that (along with proper GPL header).
While I make it sound like GPL is the "only" acceptable license, I'll leave
it up to lawyers to determine what other appropriate license could be used
for a new driver.
<akpm@osdl.org>
[PATCH] sonypi devinit section usage
From: Stelian Pop <stelian@popies.net>
This patch removes the usage of __devinit in the srs methods of the sonypi
driver, because those functions are also called from sonypi_pm_callback().
Patch originally from Randy Dunlap.
<akpm@osdl.org>
[PATCH] VM overcommit documentation fixes
From: Andy Whitcroft <andyw@uk.ibm.com>
Whilst looking at the memory overcommit logic I noticed that the pointer to
the documentation from the *_vm_enough_memory calls is incorrect. Also
that in one instance the routine does not have the expected pointers.
<akpm@osdl.org>
[PATCH] meye driver update
From: Stelian Pop <stelian@popies.net>
This patchlet is just a resync with my tree, it only increments the meye
driver version number and makes some small comment changes as suggested by
Randy Dunlap.
<akpm@osdl.org>
[PATCH] remove_suid() should return error code
From: Nikita Danilov <Nikita@Namesys.COM>
remove_suid() ignores return value of notify_change()->i_op->setattr().
This mean, that even if file system fails to clear suid bit,
generic_file_aio_write_nolock() proceeds with write, which is unsafe.
Actually, even ext2's ->setattr() can fail, when trying to update ACL, for
example.
Attached patch modifies remove_suid() to return result of ->setattr(), and
updates in-tree callers.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: cpu_down()
Implement cpu_down(): uses stop_machine to freeze the machine, then
uses (arch-specific) __cpu_disable() and migrate_all_tasks().
Whole thing under CONFIG_HOTPLUG_CPU, so doesn't break archs which
don't define that.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Sysfs Online Attribute
Add "online" sysfs attribute to cpus to bring them up and down.
Again, only under CONFIG_HOTPLUG_CPU.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: don't pull onto offline CPUs
Don't move tasks onto offline cpus in load_balance and wake_task (the
latter is caused by a completion run from stop_machine).
Note that cpu_is_offline() is a noop when CONFIG_HOTPLUG_CPU=n.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Take cpu Lock Around Migration
Grab cpu lock around sched_migrate_task() and sys_sched_setaffinity().
This is a noop without CONFIG_HOTPLUG_CPU.
The sched_migrate_task may have a performance penalty on NUMA if lots
of exec rebalancing is happening, however this only applies to
CONFIG_NUMA and CONFIG_HOTPLUG_CPU, which noone does at the moment
anyway.
Also, the scheduler in -mm solves the race another way, so this will
vanish then.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Keep IRQs off in Migration Thread Calling
Currently the migration thread re-enables irqs, then calls
move_task_away which disables IRQs again and actually does the move.
This means there is a race where the migration thread gets preempted,
and the target CPU can go down.
Hold irqs disabled in migration thread across move_task_away(), which
now doesn't need to save flags (the other caller is the hotplug CPU
code, where irqs are also disabled).
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Set prio of migration thread before CPU
We need the migration thread to be RT as soon as the CPU comes online:
for example, stop_machine() (another RT task) expects to yield to it.
Extract the core of setscheduler() and do that when the migration
thread is created. rq lock is a precaution against the (theoretical)
possibility of someone else doing setscheduer on this thread at the
same time.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Make Migration Thread Handle CPUs Going
Change the migration thread to directly use its cpu arg, rather than
smp_processor_id(): if a cpu goes up then down rapidly, it can be on
the wrong cpu just before it is stopped.
Add code to stop the migration thread on CPU_DEAD and CPU_UP_CANCELED.
Remove the (bogus) priority of the notifier.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Read Copy Update Changes
Add hook for RCU to handle jobs on dead cpu. Requires new
tasklet_kill_immediate for RCU to clean up its tasklet (which might
have been about to run, so tasklet_kill won't work).
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Make ksoftirqd Handle CPU Going Down
Change ksoftirqd not to assume it's on the CPU: when a cpu goes down,
it will be rudely dragged off. Since do_softirq() uses
smp_processor_id(), it's easiest to disable preemption, check that the
cpu is still up, then call do_softirq().
If the cpu is actually offline, wait for the notifier, which kills us.
Take over tasklets from dead cpu in the notifier.
Clean up redundant double assignment in CPU_UP callback.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Workqueue Changes
Workqueues need to bring up/destroy the per-cpu thread on cpu up/down.
1) Add a global list of workqueues, and keep the name in the structure
(to name the newly created thread).
2) Remove BUG_ON in run_workqueue, since thread is dragged off CPU when
it goes down.
3) Lock out cpu up/down in flush_workqueue, create_workqueue and
destroy_workqueue.
4) Add notifier to add/destroy workqueue threads, and take over work.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Kswapd Changes
Keep track of kswapds: it's OK that they get moved off a node when the
last CPU goes down, but when a CPU comes back, we should try to move
the kswapd back onto its node.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Other CPU_DEAD Notifiers
Various files keep per-cpu caches which need to be freed/moved when a
CPU goes down. All under CONFIG_HOTPLUG_CPU ifdefs.
scsi.c: drain dead cpu's scsi_done_q onto this cpu.
buffer.c: brelse the bh_lrus queue for dead cpu.
timer.c: migrate timers from dead cpu, being careful of lock order vs
__mod_timer.
radix_tree.c: free dead cpu's radix_tree_preloads
page_alloc.c: empty dead cpu's nr_pagecache_local into nr_pagecache, and
free pages on cpu's local cache.
slab.c: stop reap_timer for dead cpu, adjust each cache's free limit, and
free each slab cache's per-cpu block.
swap.c: drain dead cpu's lru_add_pvecs into ours, and empty its committed_space
counter into global counter.
dev.c: drain device queues from dead cpu into this one.
flow.c: drain dead cpu's flow cache.
<rusty@rustcorp.com.au>
[PATCH] Hotplug CPUs: Remove CPU_OFFLINE Notifier
We no longer have a CPU_OFFLINE notifier: we freeze the machine and
kill the CPU atomically. Remove it.
<James.Bottomley@steeleye.com>

[PATCH] critical x86-64 merge
There were some nasty bugs in the x86-64 code, including one race that
could cause random reboots, especially on Intel machines, with the NMI
watchdog. This patch fixes them and also includes some harmless
cleanups.
Main fixes were for some buglets in the IOMMU code and the plugging of a
race in the exception stack handling. Also disables an broken MCE on K8
explicitely.
Also finally the preempt compile issues are fixed.
- Declare hpet interrupt separately in drivers/char/rtc.c
- Fix rtc.h/hpet.h to not depend on interrupt.h
- Finally include smp_lock.h in hardirq.h
- Update defconfig
- Export bad_dma_address
- Merge with 2.6.5rc2
- Never schedule on interrupt stacks.
- Add option to force software iotlb (iommu=soft)
- Add ifdefs to gsi patch to match i386 (Bjorn Helgaas)
- Fix K8 GART TLB MCE workaround to actually work
- Fix dwarf2 unwind table in SAVE_ARGS (Jim Houston)
- Disable APIC on VIA/NVidia even with acpi=off (Gwenole Beauchesne)
- Fix parsing bug in "apic" option (Gwenole Beauchesne)
- Fix dma mask handling in pci_alloc_consistent
- Make pci_alloc_consistent more robust in low memory situations.
- Print version number in oopses (from i386)
- ACPI GSI cleanup (Bjorn Helgaas)
- Disable K8 GART TLB walk error MCE explicitely
- Add support to disable individual MCEs in the various banks.

[PATCH] fix console oops/race
Finally nailed this sucker.
con_close() checks the tty->count and then sleeps in acquire_console_sem().
But another process can come in and grab a ref against the tty while
con_close() dropped the BKL. But con_close() then proceeds to deallocate the
tty->driver_data anyway, even though the tty now has ->count == 2.
Fix that by moving the check for ->tty_count inside console_sem.

- a driver might access the i2c bus from attach_adapter() which
deadlocks since all xfer routines take the lock.

[PATCH] Hack mptfusion to work on >4GB machines
fusion needs several separately allocated coherent regions and

[PATCH] kbuild ordering fix
From: Sam Ravnborg <sam@ravnborg.org>
In the i386 case we need to generate asm-offset.h, before starting building
the kernel tree. Building asm-offset.h causes us to use one of the
shorthands in the top-level makefile, namely the one for .s files. The one
that allows us to do: make some/dir/file.s
And this shorthand happens to have a dependency to scripts, therefore I did
not see this problem on i386. But David hit it with sparc64, because there
is no asm-offset.h file. No parallel stuff involved here, just an ordinary
error.

Opening a non-existing block device currently yields an ENXIO error. Doing
the same for char devices produces the correct error ENODEV.

[PATCH] make inflate use less stack space with gcc3.5

[SPARC32]: Support memory starting at physical address other than 0
From: Stefan Holst <mail@s-holst.de>
Allow physical memory to start at almost arbitrary addresses. LEON
needs it, so do SPARCstation 10/20 without slot 0 populated. Although
Sun do not support this configuration, at least some such systems can
boot with this patch.
Physical memory starting at or above 0xF4000000 is not supported.

[SPARC32]: Restore a.out binary format capability
This depended on CONFIG_SPARC, which is obsolete. Use SPARC32 instead.

[PATCH] Revert UDF inode semaphore locking
For some reason I don't understand, the last UDF filesystem update makes
the UDF deadlock when I write a bunch of mp3 files to a CDRW using the
packet writing patch. Both "cp" and pdflush get stuck in __down.
Reverting the semaphore changes makes the problem go away. Use the
kernel lock again, until whatever recursive offender gets fixed.
(The offensive recursion seems to be: write() takes the inode semaphore,
causes memory pressure, and then trying to write back the inode or dirty
data to disk tries to get the semaphore again and deadlocks.)

<torvalds@ppc970.osdl.org>
Remove stale legacy ISDN files.
From Armin Schindler <armin@melware.de>:
"These files were added in the first place for the compat
driver to the legacy isdn4linux module. Since the Eicon
driver now uses CAPI only, these files are obsolete."
<jmorris@redhat.com>
[CRYPTO]: Add setkey operation for digests.
From Jouni Malinen <jkmaline@cc.hut.fi>
Added support for using keyed digest with an optional dit_setkey handler.
This does not change the behavior of the existing digest algorithms, but
allows new ones to add setkey handler that can be used to initialize the
algorithm with a key or seed. setkey is to be called after init, but before
any of the update call(s).
<jmorris@redhat.com>
[CRYPTO]: Add Michael MIC algorithm.
From Jouni Malinen <jkmaline@cc.hut.fi>
Added Michael MIC keyed digest for TKIP (IEEE 802.11i/WPA). This algorithm
is quite weak due to the requirements for compatibility with old legacy
wireless LAN hardware that does not have much CPU power. Consequently, this
should not really be used with anything else than TKIP.
Michael MIC is calculated over the payload of the IEEE 802.11 header which
makes it easier to add TKIP support for old wireless LAN cards. An additional
authenticated data area is used (but not send separately) to authenticate
source and destination addresses.

[PATCH] ppc64: fix timebase bugs
From: Anton Blanchard <anton@samba.org>
- Consolidate printing of timebase and cpuinfo in /proc/cpuinfo, there were
many trivial differences between pseries/iseries/pmac.
- Remove ppc_md.setup_residual, no longer needed
- Fix for processors over 2.147GHz, from Jake Moilanen. We were using a
signed int to parse the OF property.
- Set some sane defaults for timebase and processor frequency if we fail to
get the correct values from OF.
<akpm@osdl.org>
[PATCH] ppc64: implement iommu=off for pseries
From: Anton Blanchard <anton@samba.org>
Implement iommu=off for pseries. We limit memory to 2GB as pmac does,
however the default for < 2GB remains iommu=on unlike pmac.

<akpm@osdl.org>
[PATCH] ppc64: implement pci_dma_error
From: Anton Blanchard <anton@samba.org>
Implement pci_dma_error. Create PCI_DMA_ERROR_CODE like sparc64, it will
allow us to find and fix out of tree drivers using NO_TCE directly.
ibmveth needs some surgery, fix it temporarily until the guys come up with
a decent fix.
<akpm@osdl.org>
[PATCH] fix device open return values
The recent conversion of the open-of-a-nonexistent-blockdev return value from

<ja@ssi.bg>
[IPVS] Fix connection rehashing with new cport
<torvalds@ppc970.osdl.org>

[PATCH] ppc32: fix build with CONFIG_MODVERSIONS
From: Paul Mackerras <paulus@samba.org>
Olaf Hering <olh@suse.de>
This adds __kcrctab to the discard list for the link script for the boot
wrapper, and is needed if you compile with CONFIG_MODVERSIONS.
With this patch applied, we need to update makefile dependencies. Otherwise
the bootfiles will remain untouched because they do not depend on the changed
linker script.

[PATCH] ppc64: iSeries virtual cd fix
From: Stephen Rothwell <sfr@canb.auug.org.au>
This patch stops an oops caused by certain ioctls being performed on the

affected.
<akpm@osdl.org>
[PATCH] ppc64: iSeries virtual console cleanup (part 1)
From: Stephen Rothwell <sfr@canb.auug.org.au>
This patch starts cleaing up (and paring down) the virtual console driver.
It does:
- viocons is NOT a serial driver
- remove unneeded empty methods
- change the console name
<akpm@osdl.org>
[PATCH] sh: update defconfigs
From: Paul Mundt <lethal@linux-sh.org>
This patch updates the sh defconfigs to use the board_defconfig format
instead of the defconfig-board format that sh was using before. Since Sam
Ravnborg already added the automated archhelp stuff that sh was using to the
top-level Makefile, the sh version can be killed off.
<akpm@osdl.org>
[PATCH] sh: port sh-sci driver to the new API
From: Paul Mundt <lethal@linux-sh.org>
This ports the sh-sci driver to the new API. sh and h8 both use this. The
intention is to leave the drivers/char sh-sci in place for a short period of
time until all the h8 people are on the new driver (sh no longer uses the
drivers/char version).
<akpm@osdl.org>
[PATCH] sh: DAC ODD driver

[PATCH] sh: DMA Mapping API
From: Paul Mundt <lethal@linux-sh.org>
This implements the DMA mapping API for sh, as well as cleaning up some
sh-specific DMA drivers.
<akpm@osdl.org>
[PATCH] sh: hugetlb support
From: Paul Mundt <lethal@linux-sh.org>
This implements hugetlb support for SH-4. SH-4 supports 1k/4k/64k/1MB pages,
since we're only interested in the 64k/1MB sizes, this is what we support.
The sh hugetlbpage code borrows heavily off of the sparc64 port, which works
fine for these cases at this point in time.
<akpm@osdl.org>
[PATCH] sh: sh-specific framebuffer updates
From: Paul Mundt <lethal@linux-sh.org>
This includes sh-specific framebuffer updates, including updates to hitfb and
pvr2fb, as well as adding sh to the pgprot_writecombine() users in fb_mmap().
<akpm@osdl.org>
[PATCH] sh: various fixes
From: Paul Mundt <lethal@linux-sh.org>
This is the rest of the sh update, which includes everything else
sh-specific, general cleanups, bugfixes, etc. Nothing really eventful.

[PATCH] Work around compiler error in proc_misc.c
From: Alan Stern <stern@rowland.harvard.edu>
A change which was recently applied to fs/proc/proc_misc.c included a comment
about splitting a seq_printf into two pieces to work around a bug in
gcc-2.95.3. Unfortunately gcc-2.96 still chokes on the statements. The
patch below makes it work better and tidies the code up a bit.
<akpm@osdl.org>
[PATCH] fbcon font cloning fix
From: Petr Baudis <pasky@ucw.cz>
This patch fixes a bug which I hit when migrating from 2.4. Basically,
when I do setfont during the system boot, the then-spawned ttys do not
retain the new font but fall back to the default one.
I've tracked that down to a clearly bogus test in fbcon_set_display(),
because vc->vc_font.width is not set at that time yet (no font has been
loaded for the new vc). But even if it would (or this was meant to test
against tmp->vc_font.width), it would mean only *HUGE* fonts would be
retained. And even if there were *two* bugs there and it was supposed to
be less-than there, I couldn't make a sense of the test.

<jbarnes@sgi.com>
[PATCH] ia64: quiet sn_serial driver
Bjorn pointed out that the sn console driver will spew printks if
compiled in even if no hardware is present. In addition to fixing
that, I took the opportunity to cleanup/correct a few other printks in
that driver.
<alex.williamson@hp.com>
[PATCH] ia64: lost sx1000 naming in sba_iommu
Mainly cosmetic, but Bjorn noticed I got a little over zealous in
cleaning out the sx1000 specific init routines in sba_iommu. This adds
back in the ID->name mapping so it doesn't show up as "Unknown".
<markgw@sgi.com>
[PATCH] ia64: deprecate SN2 linkstatd
This patch against 2.6.5-rc2 affects the SGI/SN platform only. It deprecates
a kernel daemon for our interconnect traffic statistics which has been
replaced by a userland tool.
<benh@kernel.crashing.org>
[PATCH] More pmac-zilog sleep fix
In the long story of "BenH can't get a simple fix right the first time",
please add this one to pmac_zilog, and now people should enjoy really
working sleep again on pmac laptops ...
If the serial port was closed, we could use an uninitialized "pwr_delay"
and pass that to schedule_timeout().

[SPARC64]: Handle NULL type arg properly in sys32_mount().
<paulus@samba.org>
[PATCH] Threaded core dumps for PPC32
At the moment, ppc32 kernels will oops if a threaded program tries to
dump core. We call dump_fpu with a NULL regs pointer, which it tries
to dereference.
This fixes the issue by implementing the hooks used in doing threaded
core dumps properly.
<paulus@samba.org>
[PATCH] fix ppc32 sys_swapcontext
This fixes a bug in the swapcontext system call on ppc32.
On ppc32, the system call entry only saves the volatile registers,
except in the case of a few system calls (e.g. fork) which need all the
registers saved. Swapcontext needs all the registers but we weren't
saving them all. So fixes that.
<davej@redhat.com>
[AGPGART] Mass ia32e renaming.

JFS: Prevent hang in __lock_metapage

JFS: don't use global lock in lmLogSync when local lock is sufficient
I stupidly used the global jfs_log_sem to protect log->sb_list when
implementing the shared journal stuff. Since we already hold
LOG_LOCK, it makes more sense to use that to protect log->sb_list.
This caused horrible serialization when running on lots of jfs
volumes.

[PATCH] ia64: fix name conflict with handle_exception()
I tried to build usb/gadget/file_storage.c (CONFIG_USB_FILE_STORAGE=y),
but it uses "handle_exception()" for its own purposes, which conflicts
with the ia64 definition. ia64 only uses handle_exception() within
arch code, so it seems like we ought to rename it to be ia64-specific.
done_with_exception() looks similar, so I renamed it as well, although
there's no actual conflict.

[PATCH] ppc64: getdents patch for 32 -> 64 converter
From: Anton Blanchard <anton@samba.org>
From: Marcus Meissner <meissner@suse.de>
With 2.6.4 we now have the glorious hidden d_type passing in getdents.
glibc CVS expects this to be passed if we have a kernel version after
2.6.4, so we have to also handle it in the 32bit syscall converter.

[PATCH] ppc64: SMT snooze fix in idle loop
From: Olof Johansson <olof@austin.ibm.com>
A smt_snooze_delay of 0 is supposed to mean "disabled", but current idle
loop logic doesn't take that into account and snoozes immediately instead.
Below patch fixes the logic in the idle loop, as well as cleans up the test
a bit. An idling processor might no longer see a snooze change
immediately, but that's not needed anyway.

[PATCH] ppc32: Fix racy access to TI_FLAGS
The ppc32 syscall entry code could access the thread info flags in a
racy way, thus potentially losing bits sets there at interrupt time or
by another CPU, like NEED_RESCHED or SIGPENDING (ouch !).
This fixes it by moving the potentially racy bit to a different field (I
preferred that rather than turning the access into an atomic operation
for performances reasons).

[PATCH] adbhid preempt/smp races
This fixes a few races in the LED code of the adbhid driver that would

[PATCH] powerbook via-pmu races
This fixes some racy code in the management of asynchronous brightness

<benh@kernel.crashing.org>
[PATCH] dmasound close timeout
The dmasound driver occasionally hangs a process on exit.
Apparently there is a possible case where the sound HW stops draining
output samples and the driver waits forever in its release() callback.
It should check for signals(), but it seems signal_pending() never
returns 1 when the process is beeing killed (implicit release() of files
on exit).
This patch adds a safety timeout to the release() function to make sure
we can at least close the driver. I'll try to find the reason we aren't
driving samples later, but it is better to have a safety just incase the
sound clock goes berserk for some reason.
<benh@kernel.crashing.org>
[PATCH] ppc32: arch code preempt fixes
I figured the best way to stop beeing bothered by users trying to run
preempt was to fix it ;)
Here's a first batch that close some races we had when testing regs->msr
for altivec or FPU enable, then doing the giveup_* function. A preempt
in between those would have caused us to save a stale altivec or FPU
context.

[ACPI] ACPICA 20040326 from Bob Moore
Implemented support for "wake" GPEs via interaction between
GPEs and the _PRW methods. Every GPE that is pointed to by
one or more _PRWs is identified as a WAKE GPE and by default
will no longer be enabled at runtime. Previously, we were
blindly enabling all GPEs with a corresponding _Lxx or _Exx
method - but most of these turn out to be WAKE GPEs anyway.
We believe this has been the cause of thousands of
"spurious" GPEs on some systems.
This new GPE behavior is can be reverted to the original
behavior (enable ALL GPEs at runtime) via a runtime flag.
Fixed a problem where aliased control methods could not
access objects properly. The proper scope within the
namespace was not initialized (transferred to the target of
the aliased method) before executing the target method.
Fixed a potential race condition on internal object
deletion on the return object in AcpiEvaluateObject.
Integrated a fix for resource descriptors where both
_MEM and _MTP were being extracted instead of just _MEM.
(i.e. bitmask was incorrectly too wide, 0x0F instead of 0x03.)
Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName,
preventing a fault in some cases.
Updated Notify() values for debug statements in evmisc.c
Return proper status from AcpiUtMutexInitialize,
not just simply AE_OK.

[WATCHDOG] v2.6.5-rc2 pcwd.c-patch3
Version 0.15 of pcwd.c - Changes that were made are:
* Rewrote code for exchanging commands with the ISA-PC Watchdog card
* Restructured + rewrote the init and exit code
* Added option_switches info
* Use the option_switches info to find out what the cards heartbeat is
* Added notifier support

[WATCHDOG] v2.6.5-rc2 pcwd.c-patch4
Version 0.16 of pcwd.c - Changes that were made are:
* Changed the driver so that it uses an internal timer to do
the actual watchdog pinging. This way the watchdog's emulated
'heartbeat' is usuable as a module parameter. The watchdog's
heartbeat can now vary from 2 till 7200 seconds
Tested on pcwd card with temperature option

don't seem to be needed here.

[PATCH] s390: core fixes.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
s390 core changes:
- Fix return type of some system call functions (long vs. int).
- Fix prototypes for compat system call handlers.
- Correct some bugs in the compat system call wrappers.
- Fix broken pointer arithmetic which causes problems with
gcc 3.4 and -march=z990
- Remove unnecessary #ifndef & optimize inline assemblies in spinlock.h.
- Improve handling of deferred condition code 1.
- New default configuration.
<akpm@osdl.org>
[PATCH] s390: dasd driver.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
dasd device driver changes:
- After a state change interrupt restart all running i/o on queue
and reset device timer.
- Improve some debug messages.
- Lower timeout of reserve/release/steal_lock to 2 seconds.
- Fix BIODASDPSRD ioctl.
- Replace ro_flag, use_diag_flag and disconnect_error_flag words by bits.
- Use BLKPG_DEL_PARTITION ioctl instead of a call to delete_partition because
delete_partition is not an exported function. Since dasd_destroy_partitions
can't do blkdev_get because dasd_open would fail, keep the block device
open as long as partitions exist. This in turn requires a different
approach to the open vs. offline race.
<akpm@osdl.org>
[PATCH] s390: z/VM monitor stream.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>

- icuv: clear correct field in iucv_register_program if no userid is specified.
- lcs: fix online/offline cycle again.
- lcs: fix ungrouping of lcs group device. The channels of the lcs card
should be offline afterwards.
- lcs: don't do netif_stop_queue if no tx buffer is available, just
return -EBUSY and drop the packets.
<akpm@osdl.org>
[PATCH] s390: tape driver.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
s390 tape driver changes:

- Do not use bus_id string in debug feature messages.
- Check for IS_ERR(irb) error conditions in interrupt handler.
- Fix removing tape discipline modules.

[PATCH] s390: system call speedup part 1.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
The purpose of this is to speed up system calls on s390. I managed to
squeeze about 65 cycles from each system call. This improved e.g. getpid()
from 232 to 157 cycles. As a nice side-effect it simplified the uaccess
functions considerably.

[PATCH] adjuct cpu_khz in response to cpufreq changes
From: john stultz <johnstul@us.ibm.com>
This patch ensures that cpu_khz is adjusted on cpufreq notifications even
when the tsc timesource is not in use. It fixes the mostly cosmetic issue
when using the ACPI PM timesource of /proc/cpuinfo not being properly
updated when cpu frequency was lowered.
<akpm@osdl.org>
[PATCH] selinux: check return value for receive node permission
From: James Morris <jmorris@redhat.com>
This patch fixes a bug where the return value for a permission call is not
checked.
The bug was introduced when I added some code in the following changeset:
<http://linux.bkbits.net:8080/linux-2.5/diffs/security/selinux/hooks.c@1.19?nav=index.html|src/|src/security|src/security/seli+
nux|hist/security/selinux/hooks.c>
Code was added after this line:
err = avc_has_perm(isec->sid, node_sid, SECCLASS_NODE, node_perm, NULL, &ad);
without adding an explicit check of 'err', which was previously returned
from the function rather than being checked. i.e. it would drop through
to:
out:
return err;
}
With the new code added, err can (and typically would) be overwritten with
a successful value, causing the permission check to not deny permission if
needed. The intended denial would have been logged.
The patch below fixes this problem.
<akpm@osdl.org>
[PATCH] Fix uninitialized data in EFI RTC /proc interface
From: Bjorn Helgaas <bjorn.helgaas@hp.com>
The problem is that we don't clear out the efi_time_t buffer before asking
EFI to fill it in. EFI doesn't always write the entire buffer (in
particular, the alarm time only supports one second resolution, so the
nanosecond field is often untouched).
The effect is that 'cat /proc/driver/efirtc' shows garbage in the
nanoseconds part of the alarm time, and sometimes artifacts like bogus
alarm date and junk after the actual end of the text.
<akpm@osdl.org>
[PATCH] Remove <asm/setup.h> from cmdlinepart.c
From: Bjorn Helgaas <bjorn.helgaas@hp.com>
Remove include of <asm/setup.h> from cmdlinepart.c. This is not be needed
for i386 (it builds fine with this patch), and ia64 doesn't supply a
setup.h.
asm/setup.h contains a hodge-podge of stuff with no real
consistency between architectures. It appears to be
included mainly by arch-specific drivers:
acsi (Atari disks)
amiflop (Amiga floppy)
z2ram (ZorroII ram disk)
amiserial (Amiga serial)
...
and under arch-specific #ifdefs:
fbcon (under __mc68000__ or CONFIG_APUS)
fonts (ditto)
logo (CONFIG_M68K)
...

smp_processor_id is to be used when current_thread_info()->cpu is

export to modules what's really needed. smp_processor_id is not
model-specific, so we no longer need btfixups for it.

[PATCH] USB: Eliminate wait following interface unregistration
This patch from Alan Stern <stern@rowland.harvard.edu> fixes a bug in
the current USB code that causes khubd to hang when a device is removed
from the system, thereby preventing any future USB device changes (like
adding or removing other devices) from happening.
Both Andrew and I can easily duplicate this bug against the current -bk
tree.
It's not a perfect fix, but it works for now, and I will spend the next
week working on restructuring the code so this is handled properly.

A few asm/types.h test a config variable without including

[PATCH] ppc32: More preempt fixes
This patch fixes more cases of possible preempt issue when testing

that I missed in my previous round of fixes (bk get helps before
grepping ;)
I also change the single step and program check exceptions to not
re-enable interrupts right away on C code entry, it was useless and
would cause interesting issues with preempt & xmon

[PATCH] ppc64: syscall error test incorrect for 64 bits results
The syscall return path on ppc64 checks if the error is between
-LAST_ERRNO and 0, if it is, does the usual inversion along with
setting a CR bit indicating to glibc that an error occured.
However, we had an interesting bug where we used a 32 bits logica
(unsigned) comparison, thus possibly doing false positives for
valid 64 bits unsigned values whose low 32 bits happen to be in
the error range.
Fix that.

[PATCH] Fix slab creation/destruction vs. CPU Hotplug
From: Rusty Russell <rusty@rustcorp.com.au>
From: Srivatsa Vaddagiri <vatsa@in.ibm.com>
Hit a couple of (cpu hotplug) races in slab allocator during my tests.
Mostly it was because of continuous loading/unloading fs/minix/minix.ko
while simultaneously doing offline/online of CPUs. As part of its init and
exit routines, minix.ko create/destroys caches, which lead to several
oopses.
1. kmem_cache_create
In brief, kmem_cache_create does:
a) calls enable_cpucache to create per-cpu cache for all
online CPUs.
b) adds the cache to the global list of caches
These two are not done atomically and thats what causes problems.
For ex: lets say that at the time of step a) CPU1 is not online.
Hence no per-cpu cache is created for CPU1 (cachep->array[1] is NULL).
However CPU1 is not completely dead in the sense that CPU_DEAD
processing for it is not yet over. By the time CPU_DEAD processing
starts for CPU1, step b) is complete. So cpuup_callback finds this
cache and tries freeing it's per-cpu cache associated with CPU1.
In the process it dereferences a NULL pointer and dies.
2. kmem_cache_destroy
In brief, kmem_cache_destroy does:
a) deletes the cache from the global list of caches
b) Drain per-cpu cache (drain_cpu_caches), which
basically uses smp_call_function to run do_drain
on all online CPUs.
One possible race is let's say that CPU1 is coming up.
By the time CPU_UP_PREPARE is processed for CPU1, step a) is
complete. Hence cpuup_callback does not allocate any per-cpu cache
for the cache that is being destroyed.
However by the time step b) is run, CPU1 is completely online
(taking interrupts). It receives the IPI and tries draining
it per-cpu cache (which is NULL) and dies there.
I think we need to serialize kmem_cache_create/destroy against CPU hotplug
to prevent these problems. Patch below does that by taking CPU Hotplug sem
(which is OK since kmem_cache_create/destroy are not very frequently
used?).

[PATCH] inode dirtying timestamp fix
It's a bit late in 2.6.5-rc for this, but it does fix a significant bug: for
the first five minutes after boot, prior to the jiffy wrap, /bin/sync doesn't
write all of the dirty data.
We currently record an inode's time-of-first-dirtying in the address_space.
This causes a few problems with dirty block special inodes: when the device
node for /dev/hda1 needs to be written back we bogusly inspect the timestamp
for the address_space, which belongs to a different inode.
So move the inode's dirtying time up into the inode itself.
This means that for block-special inodes, inode->dirtied_when represents the
time at which the inode itself was dirtied.
For regular files it represents the time at which the inode or its pages were
dirtied.
For blockdevs, the time-of-first-dirtying is recorded in the kernel-internal
blockdev inode. Only I_DIRTY_PAGES makes sense on these inodes.
The reason all this works is that when dirtying a page we always run
__mark_inode_dirty(page->mapping->host);
which refers to the kernel-internal blockdev inode.

[PATCH] fix SATA simulation of 6-byte read/write
Here's one for -rc... either this bit is assumed on most modern drives,
or nobody uses the 6-byte commands for read/write (which is very
likely). Either way it definitely wants fixing.
Since we use the modern "LBA" method of addressing sectors, this bit
must be present in the Device register when issuing a read or write.
There are three code paths that need this bit, and only two of them
actually set it. This patch fixes the third (and apparently never used)
code path.

[SPARC32]: Update module linking for symbols starting with "."
Rusty did not like the __dot_sym approach and suggested instead:

extern int rem(int, int) __attribute__((weak,alias(".rem")));
2) EXPORT_SYMBOL(rem) etc.
3) Check genksyms recognises that prototype (it should).
4) Copy "dedotify" from ppc64 to handle them on load.
The only real downside is the risk that someone else will export
those names, but I think that's pretty unlikely.

[PATCH] Fix BLKPREP_KILL
From: Jens Axboe <axboe@suse.de>
Samuel Rydh wrote:
If a MODE_SENSE(6) command is sent to an IDE cd using the CDROM_SEND_PACKET
ioctl, then the kernel freezes solidly. To reproduce this, one can take the
SCSI cmd [1a 08 31 00 10 00] and a 16 byte data buffer.
After some bug hunting, I found out that the following is what happens:
- ide-cd recognizes that MODE_SENSE(6) isn't supported and tries
to abort the request from ide_cdrom_prep_pc by returning BLKPREP_KILL.
- in elv_next_request(), the kill request is handled by
the following code:
while (end_that_request_first(rq, 0, rq->nr_sectors))
;
end_that_request_last(rq);
The while loop never exits. The end_that_request_first() doesn't do anything
since rq->nr_sectors is 0; it just returns "not-done" after handling those 0
bytes (rq->bio->bi_size is 16).

A couple of drivers can sometimes fail the first segments in a bio then

CPUs.
- Remove dssall in the assembly calls and do it now once in switch_mm
(stop vmx streams). Assume the G5 doesn't need a sync after dssall.
- Remove bogus isync in the loop setting the userland segment registers
- Do not switch the userland segments when the mm stays the same

[PATCH] ppc32: Allow PREEMPT with SMP in KConfig
On ppc32, CONFIG_PREEMPT wasn't settable along with CONFIG_SMP

domain
<benh@kernel.crashing.org>
[PATCH] ppc64: Add a sync in context switch on SMP
For the same reason as ppc32, we need to ensure that all stores
done on a CPU has reached the coherency domain and are visible

thread may be rescheduled almost right away there.

[PATCH] back out sysfs reference count change
This backs out Maneesh's sysfs patch that was recently added to the
kernel.
In its defense, the original patch did solve some fixes that could be
duplicated on SMP machines, but the side affect of the patch caused lots
of problems. Basically it caused kobjects to get their references
incremented when files that are not present in the kobject are asked for
(udev can easily trigger this when it looks for files call "dev" in
directories that do not have that file). This can cause easy oopses
when the VFS later ages out those old dentries and the kobject has its
reference finally released (usually after the module that the kobject
lived in was removed.)
I will continue to work with Maneesh to try to solve the original bug,
but for now, this patch needs to be applied.

[PATCH] ppc64: clean up virtual <-> absolute code
From: Anton Blanchard <anton@samba.org>
Rusty Russell <rusty@rustcorp.com.au>
The iSeries has an arch-specific mapping from physical <-> absolute
addresses. Fortunately this is only used in a few places. However, the
following arch-specific macros/functions are provided in addition to the
standard macros:
__a2p()
__a2v()
__p2a()
__p2v()
__v2a()
__v2p()
absolute_to_phys()
phys_to_absolute()
virt_to_absolute()
absolute_to_virt()
Reduce them to these, with slightly shorter names, and taking either pointers
or unsigned long (as per __va and __pa) rather than making the caller cast:
abs_to_phys()
phys_to_abs()
And helper macros:
virt_to_abs()
abs_to_virt()
As is standard, virtual addresses are returned as void *, physical and
absolute as unsigned long.
Note that the change the iSeries_setup is a little subtle: ea is set to
__va(pa) above, so "phys_to_abs(pa)" is the same as "virt_to_abs(ea)".
Also, REALADDR is renamed to ISERIES_HV_ADDR and used in a couple of places
where appropriate.

[PATCH] ppc64: bugfix for hugepage support

[PATCH] ppc64: allow MAP_FIXED hugepage mappings
From: David Gibson <david@gibson.dropbear.id.au>
On PowerPC64 the "low" hugepage range (at 2-3G for use by 32-bit processes)
needs to be activated before it can be used. hugetlb_get_unmapped_area()
automatically activates the range for hugepage mappings in 32-bit processes
which are not MAP_FIXED. However for MAP_FIXED mmap()s, even at a suitable
address will fail if the region is not already activated, because there is
no suitable callback from the generic MAP_FIXED code path into the arch
code.
This patch corrects this problem and allows PPC64 to do MAP_FIXED hugepage
mappings in the low hugepage range.

Two problems:

The main thrust is to ensure that VM_ACCOUNT actually only gets set on
vma's which are indeed accountable. With that ensured much of the rest
comes out in the wash. It also removes the hugetlb memory for the

[PATCH] ksoftirqd: missing barrier
Spotted by Andrea: we need the barriers in there to prevent reads passing
ahead of the setting of current->state.

[PATCH] Replace MAX_MAP_COUNT with /proc/sys/vm/max_map_count
From: David Mosberger <davidm@napali.hpl.hp.com>
Below is a warmed up version of a patch originally done by Werner Almesberger
(see http://tinyurl.com/25zra) to replace the MAX_MAP_COUNT limit with a
sysctl variable. I thought this had gone into the tree a long time ago but
alas it has not and as luck would have it, the hard limit bit someone today
once again with a large app on a large machine.
Here is a small test app:

[PATCH] loop setup calling bd_set_size too soon
From: Chris Mason <mason@suse.com>
I think Andrew and I managed to mismerge the loop setup race fix.
loop_set_fd is using get_capacity() to read the size of the disk and
sending that to bd_set_size.
But, it is doing this before calling set_capacity, so the size being used
is wrong. This should clean things up.

[PATCH] run page_address_init() earlier
If someone runs page_address() before page_address_init(), the kernel locks
up over uninitialised spinlocks.
This only happens with the 4:4 patch, but it is more robust to run
page_address_init() before setup_arch(). page_address_init() simply
initialises statically allocated storage.

[PATCH] Fix swp_entry_t encoding
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
This fixes a problem in sys_swapon that can cause the creation of invalid
swap ptes. This has its cause in the arch-independent swap entries vs.
the pte coded swap entries. The swp_entry_t uses 27 bits for the offset
and 5 bits for the type. In sys_swapon this definition is used to find how
many swap devices and how many pages on each device there can be. But the
swap entries encoded in a pte can be subject to additional restrictions due
to the hardware besides the 27/5 division of the bits in the swp_entry_t
type. This is solved by adding pte_to_swp_entry and swp_entry_to_pte calls
to the calculations for maximum type and offset.
In addition the s390 swap pte division for offset/type is changed from 19/6
bits to 20/5 bits.

[PATCH] kbuild: $LANG fix
From: Sam Ravnborg <sam@ravnborg.org>
Fix this:
Building modules, stage 2.
MODPOST
LANG := en_US.UTF-8
make: LANG: Command not found
make: *** [all] Error 127
by removing the tab in front of the LANG assignment.

[ARM] Update ARM makefiles
- Use -march=armv6 where available.
- CFLAGS_BOOT isn't needed - the decompressor uses CFLAGS, remove it.
- PROCESSOR is never used, remove it.
- LDFLAGS_BLOB is never used, remove it.
- Remove MACHINE macro.
- Correct comments for include/asm-arm/.arch target.
- Copy format of include/asm symlink rule.
- Arrange for configuration to be split before making
include/asm-arm/arch symlink.
- This means that asm-offsets.s no longer depends on
include/config/MARKER.

[PATCH] PowerMac: cleanup of some scsi drivers
This patch from Christoph Hellwig does much welcomes cleanup of
the old mac53c94 and mesh SCSI drivers, removing sillycaps etc...
<James.Bottomley@SteelEye.com>
[PATCH] fix the subarch build again after ACPI breakage
The patch to check "maxcpus=N" early broke by putting maxcpus (a
variable which is only exported by mpparse.c) into
parse_cmdline_early().
The fix is to make it depend on the correct CONFIG_ option.
In the subarchitectures:
CONFIG_X86_SMP is the one that means "I want standard x86 smp code" and
that's what this should depend on.

[PATCH] ISDN Eicon driver: tasklet_kill removal
diva_os_cancel_soft_isr() may not call tasklet_kill(), because it is
interrupt context. This will be done correctly in the cleanup function
anyway.

[PATCH] PPC32: Fix thinko in arch/ppc/boot/simple/relocate.S
From: Tom Rini <trini@kernel.crashing.org>
When I was updating ppc/boot/simple/relocate.S to work on PPC_PREP systems, I
in advertantly broke 4xx systems. On classic PPC, the first three
instructions are nops, of which the first two can be overwritten. This is
not true of 4xx (or 8xx, but that's not working right now anyhow). The
following is needed to fix this.

<torvalds@ppc970.osdl.org>
Re-instate __ARCH_SI_BAND_T, to allow architecture overrides.
We default to "long" (which is what POSIX says), but since
a number of architectures have used "int" for historical
reasons, we need to allow overrides.
At least sparc64 needs this. Possibly others, but so far
architecture maintainers haven't spoken up. ppc64 and x86-64
are known to be ok with the default "long".
