Summary of changes from v2.5.69 to v2.5.70
============================================
<torben.mathiasen@hp.com>
[PATCH] PCI Hotplug: cpqphp 66/100/133MHz PCI-X support
After being put on hold for a while (needed fixes to CCISS driver, etc) I
attached a patch that adds pci-x support to the cpqphp driver in 2.5.65.
Changes:
Adds 66/100/133MHz PCI-X support.
Adds support for dynamically chaning frequency and mode.
Changes code to also blink the power LED when powering down.
Uses the IRQ from PCI config space if the ROM resource table doesn't
provide one (would previously use the same interrupt as the hotplug
controller which would lead to bad things when trying to update routing
tables). Dan Zink should have the credit for this fix.
Changes find_slot() to cpqhp_find_slot().
Uses sysfs to display speed/freq.
Some documentation updates.

[SCTP] Optimize SACK generation.
Wanted to try out profiling, so brought up oprofile. Very
suprising result of sctp_tsnmap_find_gap_ack() being one of the
hot functions. This should not be! Short-circuit by not even
calling if !has_gap.

<jgrimm@touki.austin.ibm.com>
[SCTP] Add a generic csum_copy for sctp.
Do the sctp checksum while copying.
<jgrimm@touki.austin.ibm.com>
[SCTP] short-circuit reassembly & ordering for best case.
Short circuit normal case. First check if the chunk belongs at the
end of the queue. If so, don't bother walking the entire list, just
just put at end.
<davidm@tiger.hpl.hp.com>
ia64: Patch by Alex Williamson: forward port of the 2.4 sba_iommu.

<anton@samba.org>
ppc64: use panic_on_oops sysctl
<anton@samba.org>
ppc64: use dma-window from deepest device tree node, from Dave Engebretsen
<sri@us.ibm.com>
[SCTP] getsockname()/getpeername() support for TCP-style sockets.
<jgrimm@touki.austin.ibm.com>
[SCTP] Allow private to global association.
The sctp scoping rules try to prevent accidentally sending
non-routable addresses to a peer as alternate addresses. However,
the current implementation is way too strict in that one can't
even try to send from a private address to a global address (a
pretty common real world setup with host behind NAT) even
when that's the _only_ address available.
If we find no addresses available, try looking for a private address
to send with, as a fallback.
Additionally, if we are sending with only a single address, don't
bother embedding this address in the INIT/INIT-ACK chunk.
<jgrimm@touki.austin.ibm.com>
[SCTP] Use GFP_ATOMIC, while we holding the local_addr_lock.
<alex_williamson@hp.com>
[PATCH] ia64: fix GENERIC build
This fixes a couple problems with the generic target in the latest
2.5.67 kernel. First is simply a fix for the addition of readX in
the machvec. The second gets things to link in roughly the same order
when using a generic vs zx1 flavor. With the current code, sba_init()
is called in the right place when using a zx1 flavor kernel, but
happens way too early on a generic kernel.
<alex_williamson@hp.com>
[PATCH] ia64: small ACPI fix
This fix is needed to boot on Intel-based machines.
<jgrimm@touki.austin.ibm.com>
[SCTP] Fix ipv6 addressing bug.
We are incorrectly using the rt6->rt6i_dst as our destination
address, resulting in bogus dst address when requiring a gateway.
<davidm@tiger.hpl.hp.com>
ia64: Update platform INIT handler to print a backtrace.
<kochi@hpc.bs1.fc.nec.co.jp>
[PATCH] ia64: don't waste irq vectors
This patch fixes waste of interrupt vector pool by not
allocating an interrupt vector to a GSI which has no corresponding
IO SAPIC.
<davidm@tiger.hpl.hp.com>
ia64: Export hp_acpi_csr_space() for modules.
<davidm@tiger.hpl.hp.com>
ia64: Consolidate backtrace printing in a single routine (ia64_do_show_stack()).
<davidm@tiger.hpl.hp.com>
ia64: Fix _raw_read_lock() to not switch text sections. Tidy it up with the
help of ia64_fetchadd() macro. Ditto for _raw_read_unlock().
<mochel@osdl.org>
Driver model: doc updates.
From Geert Uytterhoeven
<mochel@osdl.org>
kobject: Add better debugging for failed registrations.
From Steve Hemminger (shemminger@osdl.org)
<Matt_Domsch@dell.com>
Device Driver Dynamic PCI Device IDs
Provides a mechanism to pass new PCI device IDs to device drivers
at runtime, rather than relying only on a static compiled-in list
of supported IDs.
For each driver which has a pci_driver->probe routine, two things
are added: a probe_it file, and a dynamic_id directory. In the
dynamic_id directory is a new file, new_id.
/sys/bus/pci/drivers/e100
|-- dynamic_id
| `-- new_id
`-- probe_it
One may read the new_id file, which by default returns:
$ cat new_id
echo vendor device subvendor subdevice class classmask
where each field is a 32-bit value in ABCD (hex) format (no leading 0x).
Pass only as many fields as you need to override the defaults below.
Default vendor, device, subvendor, and subdevice fields
are set to FFFFFFFF (PCI_ANY_ID).
Default class and classmask fields are set to 0.
One may write new PCI device IDs into the new_id file:
echo "8086 1229" > new_id
which will cause a new device ID (sysfs name 0) to be added to the driver.
/sys/bus/pci/drivers/e100
|-- dynamic_id
| |-- 0
| `-- new_id
`-- probe_it
$ cat 0
00008086 00001229 ffffffff ffffffff 00000000 00000000
One can then cause the driver to probe for devices again.
echo 1 > probe_it
Individual device drivers may override the behavior of the new_id
file, for instance, if they need to also pass driver-specific
information. Likewise, reading the individual dynamic ID files
can be overridden by the driver.
This also adds an existance test field to struct driver_attribute,
necessary because we only want the probe_it file to appear iff
struct pci_driver->probe is non-NULL.
The device probing routines in pci-driver.c are enhanced to scan
first the static list of IDs, then the dynamic list (if any).
<mochel@osdl.org>
sysfs: Rewrite binary file handling.
From Matthew Wilcox.
- Remove sysfs_bin_buffer. It's a security hole.
- Remove checks for permissions; the VFS does that.
- Validate offset & count at the top level.
- Allow lower levels to return less data than was asked for.
- Allocate buffer at open & free it at close, not on each read/write.
<sri@us.ibm.com>
[SCTP] shutdown() support for TCP-style sockets.
<davidm@tiger.hpl.hp.com>
ia64: Patch by Arun Sharma: In brl_emu.c, a 64 bit value was being assigned to an
int.
<arun.sharma@intel.com>
[PATCH] ia64: make x86 shared programs work again
> It looks like dynamic x86 binaries have a problem once again (or
> still). If I try to run any shared x86 binaries, I get:
>
> $ ls.x86
> ls.x86: error while loading shared libraries: librt.so.1: cannot map zero-fill pages: Error 14
>
> Would someone take a look?
We saw this behavior with 2.5.59 also. The attached work around should
take care of the problem temporarily. Last time this happened, IA-32
programs were doing mmaps, whose size was one page bigger than the
size of the underlying file (even after rounding up the file size).
I never got a chance to figure out why glibc was doing mmaps with the
wrong size. Also, I failed to reproduce the problem with a more
recent (RH 8.0) glibc.
Which version of IA-32 glibc were you using ?
<jgrimm@touki.austin.ibm.com>
[SCTP] More typedef removals.
Continue typedef removal. Also, change sctp_chunk.num_times_sent
counter to a resent flag. There was a rather obscure, unlikely,
and in the end fairly benign bug sitting there if num_times_sent
wrapped. However, there's no need to keep this counter, as its
use was really just to know if we'd ever resent this chunk.
<bjorn_helgaas@hp.com>
[PATCH] ia64: sba_iommu workaround removal
This removes a workaround for some broken firmware that was
never released.
<bjorn_helgaas@hp.com>
[PATCH] ia64: sba_iommu vendor/function for unknown IOCs
Include id when encountering unknown IOC.
<bjorn_helgaas@hp.com>
[PATCH] ia64: sba_iommu trivial cleanup
This is mostly trivial whitespace and printk text tweaks. I did add the
segment number to a printk that previously just had the bus.
<anton@samba.org>
ppc64: chrp_progress() updates from Olof Johansson
<anton@samba.org>
ppc64: ethtool -e support, from Olof Johansson
<sri@us.ibm.com>
[SCTP] Handle accept() of a CLOSED association.
<jgrimm@touki.austin.ibm.com>
[SCTP] Track partially acked message for SEND_FAILED.
For SEND_FAILED support, we need to keep around data chunk fragments
that have been acked, where other fragments of the same message
have not. With this, Ardelle should be able to finish up the
SEND_FAILED support.
<jgrimm@touki.austin.ibm.com>
[SCTP] Fix sctp_sendmsg error path when associate fails.
<sri@us.ibm.com>
[SCTP] Return a readable event when polling on a TCP-style listening
socket with a non-empty accept queue.
<jgrimm@touki.austin.ibm.com>
[SCTP] Add some macros to clean up code.
sctp_state(asoc, STATE) // Is asoc in this state?
sctp_style(sk, STYLE) // Is sock this style?
sctp_sstate(sk, SS_STATE) // Is sock in this state?
<jgrimm@touki.austin.ibm.com>
[SCTP] Add SCTP_MAXSEG sockopt.
We'll fragment (if fragmentation not disabled) to the min of maxseg
or PMTU allowance.
<jgrimm@jgrimm.(none)>
[SCTP] Add SFR-CACC support. (Ardelle.Fan)
Submitted by Ardelle Fan. Implementation of Split Fast Retransmit -
Changeover Aware Congestion Control. Certain conditions involving
multihoming changover can result in TCP-unfriendliness. This
implements the IETF proposed method of dealing with this corner
case.

ppc64: fix some compile warnings, from Andrew Morton
<anton@samba.org>
ppc64: Fix some things that got backed out in the systemcfg merge
<anton@samba.org>
ppc64: Add loop_get_status64/loop_set_status64
<davej@codemonkey.org.uk>
[CPUFREQ] Fix powernow-k7 hang.
Some laptops don't like jumping from (for eg) 800MHz->1200MHz, but
will happily go from 800->1000->1200. The problem is caused by us
changing the FID and the VID at the same time. The spec says we have
to change them seperately. This actually buys us something extra anyway,
as we can now set the FID lazily as well as the VID.
<jgrimm@touki.austin.ibm.com>
[SCTP] Fix regression in mark_missing. (Ardelle.Fan)
Followup patch by Ardelle.
<anton@samba.org>
ppc64: Andrew Morton is picking on me
<gibbs@overdrive.btc.adaptec.com>
Aic7xxx and Aic79xx driver Update
o Avoid pre-2.5.X mid-layer deadlock due to SCSI malloc fragmentation
For pre-2.5.X kernels, attempt to calculate a safe value
for our S/G list length. In these kernels, the midlayer
allocates an S/G array dynamically when a command is issued
using SCSI malloc. This list, which is in an OS dependent
format that must later be copied to our private S/G list, is
sized to house just the number of segments needed for the
current transfer. Since the code that sizes the SCSI malloc
pool does not take into consideration fragmentation of the
pool, executing transactions numbering just a fraction of our
concurrent transaction limit with list lengths aproaching
AH?_NSEG in length will quickly depleat the SCSI malloc pool
of usable space.
Unfortunately, the mid-layer does not properly handle this
scsi malloc failure. In kernels prior to 2.4.20, should
the device that experienced the malloc failure be idle and
never have any new I/O initiated (block queue is not "kicked"),
the process will hang indefinitely. In 2.4.20 and beyond,
the disk experiencing the failure is marked as a "starved
device", but this only helps if I/O is initiated to or completes
on that HBA. If the failure was induced by another HBA, and
no other I/O is pending on the HBA and no new transactions are
queued, we are still succeptible to the hang. (Also note that
many 2.4.X kernels do not properly lock the "some_device_starved"
and "device_starved" fields calling into question their overall
effectiveness).
By sizing our S/G list to avoid SCSI malloc pool fragmentation,
we will hopefully avoid this deadlock at least for configurations
where our own HBAs are the only ones using the SCSI subsystem.
<gibbs@overdrive.btc.adaptec.com>
Aic7xxx and Aic79xx Driver Update
o Correct channel information in our /proc output.
<gibbs@overdrive.btc.adaptec.com>
Aic7xxx and Aic79xx driver updates
o Work around peculiarities in the scan_scsis routines
that could, due to having duplicate devices on our
host's device list, cause tagged queing to be disabled
for devices added via /proc.
<gibbs@overdrive.btc.adaptec.com>
Aic7xxx and Aic79xx driver updates
o Remove extra complexity and code duplication in processing
the completeq now that the completeq can be run while holding
both the ah?_lock and the done_lock.
<gibbs@overdrive.btc.adaptec.com>
Aic7xxx and Aic79xx driver Update
o Fix style nits.
<gibbs@overdrive.btc.adaptec.com>
Aic7xxx and Aic79xx Driver Updates
o Correct type safty of option parsing logic
o Make option toggling work correctly
o Add "probe_eisa_vlb" as an alias for the "no_probe" option so
that there is a clearly defined name associated with the command
line feature that allows eisa_vlb probes to be enabled/disabled
in the aic7xxx driver.
o PCI parity error checking defaults to being enabled.
<gibbs@overdrive.btc.adaptec.com>
Aic7xxx Driver Update
o Auto disable PCI parity error reporting after 10 parity errors
are observed. The user is given a loud warning message telling
them that eiter a device plugged into their motherboard or their
motherboard is not very healthy.
<gibbs@overdrive.btc.adaptec.com>
Aic79xx Driver Update
o Perform a few firmware optimizations
o Correct the packetized status handler so that
it can handle CRC errors during status data packets.
<agrover@groveronline.com>
ACPI: Update to 20030424
- Remove an unused parameter from lowlevel read/write functions
- FADT initialization cleanups
<gibbs@overdrive.btc.adaptec.com>
Aic79xx Driver Update
o Correct "Unexpected PKT Busfree" error observed under high
tag loads.
<gibbs@overdrive.btc.adaptec.com>
Aic79xx Driver Update
o Revert ahd_pause_and_flushwork() behavior so that ENSELO can
be cleared. This makes ahd_pause_and_flushwork() more effective
when the bus is hung.
<gibbs@overdrive.btc.adaptec.com>
Aic79xx Driver Upate
o Switch to handling bad SCSI status as a sequencer interrupt
instead of having the kernel proccess these failures via
the completion queue. This is done because:
- The old scheme required us to pause the sequencer and clear
critical sections for each SCB. It seems that these pause
actions, if coincident with a sequencer FIFO interrupt, would
result in a FIFO interrupt getting lost or directing to the
wrong FIFO. This caused hangs when the driver was stressed
under high "queue full" loads.
- The completion code assumed that it was always called with
the sequencer running. This may not be the case in timeout
processing where completions occur manually via
ahd_pause_and_flushwork().
- With this scheme, the extra expense of clearing critical
sections is avoided since the sequencer will only self pause
once all pending selections have cleared and it is not in
a critical section.

<jgrimm@touki.austin.ibm.com>
[SCTP] Control chunk bundling.
Control chunks should be bundled (implementor's guide advises
specifically of case were ERROR should be bundled with CE to avoid
race condition. Patch introduces a outq_cork/outq_uncork to
immediate transferral of control chunks and then release to the
packet bundling code.

Sorry, wrong patch. We need to read COMMAND after doing

[PATCH] split private and public scsi headers
Two new headers:
scsi_priv.h - for macros/declarations private to the scsi midlayer
(= not EXPORT_SYMBOL()ed)
scsi_logging.h - for SCSI_LOG_* and friends, semi-private to the
midlayer and the upper drivers. One abuse of this

[PATCH] kill pcmcia driver bind_info horror
Currenty pcmcia drivers do a loop on their devices for issuing a
SCSI_IOCTL_GET_IDLUN ioctl from kernelspace and passing dev->type
to userspace so cardmgr can guess the the dev_t and find the
device node of it.
But it doesn't actually use it but only pass it as optional arguments
to it's poor-man's hotplug scripts. So kill this horror of, we
have proper hotplug scripts in 2.5. And here we go, the first big
host->my_devices abuser is gone.

[PATCH] scsi_requeuest_fn
Okay, when doing some other stuff I looked over this one, and it's
a bit confusing to read:
- using a goto completed where a simple break would be sufficient
- using for (;;) for a perfectly fine while loop
- ...
but what's more interesting is that the spinlock handling in here,
when we switch from sdev_lock/queue_lock to host_lock we
do a spin_unlock_irq followed by a spin_lock_irqsave - but we
we just enabled interrupts so the save isn't nessecary at all, even
more we can just do spin_unlock/spin_lock when keeping them
disabled. Also we drop host_lock in the middle of this function,
just to reacquire it a tad later in scsi_dispatch_cmd, but fixing
that need a bit more thinking as there's another caller for
scsi_dispatch_cmd.

[PATCH] USB: ehci i/o watchdog
This patch adds a new "I/O watchdog" role to the existing

tweak the timer appropriately.
The patch should help with these reported problems.
(a) Bulk I/O sometimes seems to stop progressing. Not
trouble in itself, but usb-storage and scsi could
wedge deeply because of bugs in their fault recovery;
and then the problems could break khubd and rmmod...
(b) Some periodic transfers need to be "jumpstarted".
Usually seen with a high speed hub.

[PATCH] remove scsi_device proc printing from drivers
A bunch of drivers contain loops over host->my_devices in their

Kill those, the ones that actually add additional information

BTW, does someone have opintions on reading of /proc/scsi/scsi?
It's just a duplication of the sysfs tree so it should probably
go away also. OTOH there's a slightly higher chance on userland
actually using this than for the LLDDs..

Oookay - I really got upset by that tmeplates in headers crap when

gazillion kernel releases drivers like gdth I've kept them.
This means a driver works fine without any problems for all modular
builds and builtin kernel >= 2.4.0. If you want certain drivers
to work with 2.0/2.2 statyic builds too I can hack something up for
you, but I'd prefer not supporting stuff like that anymore.
Tested by compiling all drivers with make -k and not getting more
warnings than before :)

[PATCH] ia64: fix timer interrupts getting lost
This patch fixes the issue of some CPUs not showing timer interrupts

seen the problem on 2.4, but a quick looks seems like it's potentially
an issue there too.
<alex_williamson@hp.com>
[PATCH] ia64: interrupt fixes/cleanup
Here's some cleanups/fixes/changes for interrupts on 2.5.67 + ia64.
Specifically:
- Cleanup some ugliness with polarity/trigger setup.
- Add iosapic_enable_intr() to set_rte on an interupt when the
device is enabled. IMHO, we really only want to unmask RTEs
for PRTs we might actually use. This moves the interrupt
distribution here too.
- When changing a vector from edge to level, call register_intr()
to do it so all the data structures get set correctly. If we
have to guess how to setup an interupt and get it wrong, this
should close some holes in changing it back to the correct type.
- Register the HCDP interrupt in 8250_hcdp - this is where we have
to guess the polarity/trigger. The real handler will get fixed
up via PCI setup or ACPI namespace serial support, this gets it
associated w/ the port at setup. This should allow interrupts
to work when using builtin UARTs as console on HP Itanium2 boxes.

[PATCH] ia64: multi-ioport space support
This has been in my 2.4 BK tree for a while, but I should have
posted it in case there's feedback from other people working
on large machines. So here it is, in four parts:
1 enhance __ia64_mk_io_addr(port)
2 enhance pcibios_scan_root to get multiple mem & io windows
from ACPI _CRS, and fixup all the resources
3 add support for /proc/iomem and /proc/ioports
4 trivial (whitespace, copyright, and move pcibios_fixup_device_resources
closer to related code)
The current scheme is that IO ports are 64 bits, with the low 24
bits being the port number within an IO port space, and the upper
bits identifying the space. There is currently a limit of 16
spaces.

This is a trivial patch that makes sba_iommu recognize a new IOC.
Only change is that it will print
IOC: sx1000 0.1 HPA 0xf8120002000 IOVA space 1024Mb at 0x80000000
instead of
IOC: Unknown (103c:127c) 0.1 HPA 0xf8120002000 IOVA space 1024Mb
at 0x80000000

[PATCH] ia64: vendor-specific ACPI resource cleanup
This is to
- handle _CRS with multiple vendor-specific resources
- use acpi_walk_resources() instead of doing it by hand
- make lookup of vendor resource by GUID generic
- cleanup now-unused helper functions
(This depends on the previous IO port space patches, because
they removed the last of acpi_get_addr_space()).
My hope is that acpi_vendor_resource_match() and
acpi_find_vendor_resource() can someday move into ACPI,
but that probably depends on getting the idea of labelling
vendor resources with a GUID into the spec. HP does this
and I think is working on putting it in the spec.

[PATCH] ia64: fixes for semtimedop() ia32-compat handling
Here are two fixes for the ia32-compatibility mode handling
for the new semtimedop() system call for the ia64 architecture.
The first problem was that treatment of user-mode calls to semtimedop()
with a NULL 4th (struct timespec *) parameter was inconsistent with the
behavior of the same executable on i386 and also with a natively compiled
ia64 binary. A NULL 4th arg to semtimedop() should result in no timeout
being used (like a straight semop() call) rather than in an EFAULT error.
The second problem was that a legitimate semtimedop() with a timeout was
also resulting in an EFAULT because the fetch of the internal timespec
strucure by sys_semtimedop() from semtimedop32()'s kernel stack was
treated as an invalid user-data reference. This requires temporarily
switching the addressing limit with set_fs(), further requiring that
appropriate parameter checking by performed prior to the switch.
The const qualifier was removed from the (struct compat_timespec *) arg
to semtimedop32() so that the call to get_compat_timespec() wouldn't
generate a compilation warning.

[PATCH] i2c #1/3: listify i2c core
This is the first of tree patches for i2c. Trying to get the i2c
cleanups finshed before 2.6.x, so we (hopefully) don't have a
ever-changing i2c subsystem in 2.7.x again (which is very annonying for
driver maintainance).
Changes:
* listify i2c-core, i.e. make it use <linux/list.h> instead of
statically-sized arrays, removed lots of ugly code :)
* added i2c_(get|put)_adapter, changed i2c-dev.c to use these
functions instead maintaining is own adapter list.
* killed the I2C_DF_DUMMY flag which had the strange semantics to
make the i2c subsystem call driver->attach_adapter on detaches.
Added a detach_adapter() callback instead.
* some other minor cleanups along the way ...
<kraxel@bytesex.org>
[PATCH] i2c #2/3: add i2c_clients_command
Changes:
* adds a i2c_clients_command() function to i2c-core which calls
the ->command() callback of all clients attached to a adapter.
* make bttv + saa7134 drivers use that function instead of mucking
with the i2c_adapter struct themself.
<kraxel@bytesex.org>
[PATCH] i2c #3/3: add class field to i2c_adapter
This is the last of three patches for i2c. It introduces a new field
to i2c_adapter which classifies the kind of hardware a i2c adapter
belongs to (analog tv card / dvb card / smbus / gfx card ...). i2c chip
drivers can use this infomation to decide whenever they want to look for
hardware on that adapter or not. It doesn't make sense to probe for a
tv tuner on a smbus for example ...

[PATCH] remove scsi_slave_attach/scsi_slave_detach
I added those two to factor out common code from the upper drivers
a long time ago, but after Doug & Lubens nice work there's nothing
left but incrementing/decrementing a counter in struct scsi_device
that's never used except in the case were we not it must be NULL
because we just walked the chain of drivers to detach every single
one..
<hch@lst.de>
[PATCH] first batch of shost sysfs fixes
(a) scsi_check_device_busy() is unused now, kill it. Btw, although I

in scsi_remove_host now..
(b) make shost_class static to scsi_sysfs.c, with the new device model
changes no LLDD needs this anymore
(c) move private prototypes where they belong.
BTW, Mike, did I miss something or will your changes make every driver
converted to scsi_add_host & co OOPS on removal now?

<markh@osdl.org>
[PATCH] New aacraid driver fixed.
I have the new aacraid driver working on my system now. The patch is
against the 2.5.66 updates that you gave me. I made the following
changes:
aachba.c aac_scsi_cmd()
There was a race accessing the scsicmd pointer accessing the host_lock.
I made a local pointer to the Scsi_Host so the spin_lock_irq after
aac_read wouldn't panic. I think that sometimes the I/O would be done
and the memory freed before returning invalidating the scsicmd pointer.
I made the same change in aac_io_done in case scsi_done had freed the
scsicmd memory before returning.
comminit.c aac_alloc_comm()
AdapterFibsVirtualAddress was set to the virtual address of base. I
changed it to set it to the phys address. I compared this to code
pointed to by matt domsch on the aacraid devel list on the 5th. Its
aac_alloc_comm sets this variable to the phys address. This fixed the
probelem where the entry->addr was bad. Another was to fix it I guess
would be to leave this change alone and not try to convert the address
in aac_command_normal.
dpcsup.c aac_response_normal()
Changed the bus_to_virt to the calculation we talked about last month.
dpcsup.c aac_command_normal()
Changed the bus_to_virt to the calculation.
<torvalds@home.transmeta.com>
Use "__attribute__" consistently.

bit more (yay, all the copyright paperwork completed!)

[PATCH] generic subarchitecture for ia32
From: Andi Kleen <ak@muc.de>
This patch adds an generic x86 subarchitecture. It is intended to provide
an dynamic interface for APIC drivers. There are already three subarchitectures
(bigsmp, summit, default) that only differ in how they drive the local APIC.
A fourth - Unisys ES7000 - is scheduled to be merged soon.
The subarchitecture concept separated this nicely, but it has the big
drawback that they are compile time options. A Linux vendor cannot
ship own binary kernel rpms for all of these machines. Runtime probing
is needed instead.
This patch adds a new "generic" subarchitecture that just acts as a
dynamic switching layer for APIC drivers. It only tries to virtualize
the APICs, no attempt is made to cover further incompatiblities.
This means machines like the Visual Workstation, pc9800 or
Voyager are not covered; but these are unlikely to be supported by
binary distributions anyways.
The generic arch reuses the existing interface in mach_ipi / mach_mpparse.h /
mach_apic.h and just pulls it using some macros into an "struct genapic"
object. The main APIC code does not recognize it, it is all hidden
in the mach-generic include files.
Auto detection of APIC types is supported in the usual way used by
existing ports like Summit - checking ACPI or mptables for specific
signatures - or it can be specified by the user using a new "apic="
boot option. I also moved the DMI scan to before the generic
subarchitecture probe, so DMI could be used in future too to probe
specific machines.
Some minor hacks were needed to avoid circular declaration of a few
symbols, but overall it's fairly clean.
The patch has been tested on a Summit machine, an generic 4 virtual CPUs
Xeon and on an ES7000.

[PATCH] Fix .altinstructions linking failures
From: Andi Kleen <ak@muc.de>
Some configs didn't link anymore because they got references from

easily possible. This patch just discards .text.exit at runtime instead of
link time to avoid this.
It will also fix a related problem with .eh_frame in modern gcc (so far only
observed on x86-64, but could happen on i386 too)

[PATCH] slab: initialisation cleanup and oops fix
From: Manfred Spraul <manfred@colorfullife.com>
attached is the promised cleanup/bugfix patch for the slab bootstrap:
- kmem_cache_init & kmem_cache_sizes_init merged into one function,
called after mem_init(). It's impossible to bring slab to an operational
state without working gfp, thus the early partial initialization is not
necessary.
- g_cpucache_up set to FULL at the end of kmem_cache_init instead of the
module init call. This is a bugfix: slab was completely initialized,
just the update of the state was missing.
- some documentation for the bootstrap added.
The minimal fix for the bug is a two-liner: move g_cpucache_up=FULL from
cpucache_init to kmem_cache_sizes_init, but I want to get rid of
kmem_cache_sizes_init, too.

[PATCH] Don't use devfs names in disk_name()
From: Christoph Hellwig <hch@lst.de>
disk_name() (and hence bdevname()) are now returning devfs-style device names
when devfs is enabled.
This is nice, but these names are very long, and they overflow the 32-char
buffers which these functions use.
The choices are:
a) Use a bigger buffer (increase BDEVNAME_SIZE).
This might be practical. But how big?
b) return the name in kmalloced memory, make caller free it up. Yuk.
c) Add a print_bdevname() thing and intersperse that amongst the printk's.
This would work.
d) Just print the non-devfs device name. That's what this patch does.

devfs_handle_t devfs_register(devfs_handle_t dir,
const char *name, unsigned int flags,
unsigned int major, unsigned int minor,
umode_t mode, void *ops, void *info)
Of these:
- dir and flags are always zero
- the return value is never used
- info is only used in one driver which doesn't even need it for
operation
- umode_t always describes a character device
- name very often comes from a stack buffer we sprintf'ed into
so obviously we really want a much simpler API instead. My first draft for
this was:
int devfs_mk_cdev(dev_t dev, umode_t mode,
struct file_operations *fops, void *info,
const char *fmt, ...)
this removes the unused argumens, switches to a proper dev_t for the device
number and allows to directly use a printf-like expression as name, getting
rid of the temporary buffers.
Now Al has reappeared and put the first steps of his CIDR for charater device
on public ftp and we'll soon have a similar lookup object + fops mechanism in
generic code as we already habe for blockdevices, i.e. the devfs code to
assign fops from an entry will become superflous as generic code already does
it. That means the fops and info arguments are obsolete before they were
introduced, so I'd like to propose the following API instead:
int devfs_mk_cdev(dev_t dev, umode_t mode, const char *fmt, ...)
which is much nicer anyway. The educated reader will notice that this is
exactly the same prototype devfs_mk_bdev has so I'll probably get suggestions
to merge those two into some kind of devfs_mk_node soon. Personally I don't
like that as character and blockdevices are two really separate entinities
and I'll like to keep them as separate as possible.
Example patch that introduces the API and converts drivers/input attached.
Every driver which calls devfs_mk_cdev (about 50) needs conversion. Note
that the transition can happen in pieces - devfs_register continues to work
after this patch, it's just the plan to get rid of it in the end.

[PATCH] remove partition_name()
From: Christoph Hellwig <hch@lst.de>
partition_name() is a variant of __bdevname() that caches results and
returns a pointrer to kmalloc()ed data instead of printing into a buffer.
Due to it's caching it gets utterly confused when the name for a dev_t
changes (can happen easily now with device mapper and probably in the
future with dynamic dev_t users).
It's only used by the raid code and most calls are through a wrapper,
bdev_partition_name() which takes a struct block_device * that maybe be
NULL.
The patch below changes the bdev_partition_name() to call bdevname() if
possible and the other calls where we really have nothing more than a dev_t
to __bdevname.
Btw, it would be nice if someone who knows the md code a bit better than me
could remove bdev_partition_name() in favour of direct calls to bdevname()
where possible - that would also get rid of the returns pointer to string
on stack issue that this patch can't fix yet.

[PATCH] dvbdev fixes
From: Monchi Abbad <kernel@axion.demon.nl>
I found a mistake in the dvbdev.c file when creating the dvb /devfs files,
it created /dev/dvb/adapter0device0 instead of /dev/dvb/adapter0/device0.
But here is a simple fix.

[PATCH] access_ok() race fix for 80386.
From: Manfred Spraul <manfred@colorfullife.com>
Real 80386 cpus ignore the write protected bit in the page tables when
running in supervisory mode. Thus the write protected bit must be checked by
software. The current implementation does that check during access_ok().
This can result in data corruptions, if kswapd starts a swap-out between the
access_ok and the actual write operation.
To fix this, the patch moves the check from access_ok() into
__copy_to_user_ll(), and redirects all user space writes into
__copy_to_user_ll(). The patch only affects kernels build for 80386 cpus.
Additionally, the patch removes the dead prototypes for __put_user_{1,2,4,8}.
Due to the uninlining of access_ok, the .text segment is now ~ 8 kB shorter.

[PATCH] hold i_sem on swapfiles
If a swapfile is ftruncated while in use, subsequent swapout will scribble on

[PATCH] remove unnecessary PAE pgd set
From: Dave Hansen <haveblue@us.ibm.com>, Bill Irwin
With PAE on, there are only 4 PGD entries. The kernel ones never change,
so there is no need to copy them when a vmalloc fault occurs. This was
this was causing problems with the split pmd patches, but it is still
correct for mainline.
Tested with and without PAE. I ran it in a loop turning on and off 10 swap
partitions, which is what excited the original bug.

[PATCH] account for slab reclaim in try_to_free_pages()
try_to_free_pages() currently fails to notice that it successfully freed slab
pages via shrink_slab(). So it can keep looping and eventually call
out_of_memory(), even though there's a lot of memory now free.
And even if it doesn't do that, it can free too much memory.
The patch changes try_to_free_pages() so that it will notice freed slab pages
and will return when enough memory has been freed via shrink_slab().
Many options were considered, but must of them were unacceptably inaccurate,
intrusive or sleazy. I ended up putting the accounting into a stack-local
structure which is pointed to by current->reclaim_state.
One reason for this is that we can cleanly resurrect the current->local_pages
pool by putting it into struct reclaim_state.
(current->local_pages was removed because the per-cpu page pools in the page
allocator largely duplicate its function. But it is still possible for
interrupt-time allocations to steal just-freed pages, so we might want to put
it back some time.)

[PATCH] slab: additional debug checks
From: Manfred Spraul <manfred@colorfullife.com>
below is the promised patch for better slab debugging, against 2.5.68-mm4:
Changes:
- enable redzoning and last user accounting even for large objects, if
that doesn't waste too much memory
- document why FORCED_DEBUG doesn't enable redzoning&last user accounting
for some caches.
- check the validity of the bufctl chains in a slab in __free_blocks.
This detects double-free error for the caches without redzoning.

[PATCH] reduced overheads in fget/fput
From: Dipankar Sarma <dipankar@in.ibm.com>
fget() shows up on profiles, especially on SMP. Dipankar's patch
special-cases the situation wherein there are no sharers of current->files.
In this situation we know that no other process can close this file, so it
is not necessary to increment the file's refcount.
It's ugly as sin, but makes a substantial difference.
The test is
dd if=/dev/zero of=foo bs=1 count=1M
On 4CPU P3 xeon with 1MB L2 cache and 512MB ram:

[PATCH] select() speedup
From: Christoph Hellwig <hch@infradead.org>
Originally by David Mosberger, testing by Roger Luethi. From the ia64 tree.
Basically, it avoids going to memory all the time. What this does is make
life a lot easier for gcc, so it can actually do a decent amount of
optimization. The restructuring clearly is less important for out-of-order
CPUs, but even there it gives some benefits.
More specifically, the loop is now structured to operate one "unsigned long"
at a time, rather than one bit at a time. Of course, you still need to
process all the bits, but most of the relevant state in the inner loop can be
kept in registers.
Roger Luethi measured the routine on a bunch of different machines (mostly
x86, IIRC: P5, P6, Crusoe, Athlons) and performance improved there, too (and
it should definitely improve performance on any RISC-like architecture).
Roger's benchmarking results (vs number of fd's):

[PATCH] Move security_d_instantiate hook calls
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch moves the security_d_instantiate hook calls in d_instantiate and
d_splice_alias after the inode has been attached to the dentry. This
change is necessary so that security modules can internally call the
getxattr inode operation (which takes a dentry parameter) from this hook to
obtain the inode security label.

[PATCH] ext3 xattr handler for security modules
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch against 2.5.68 implements an xattr handler for ext3 to support the
use of extended attributes by security modules for storing file security
labels. As per the earlier discussion of extended attributes for security
modules, this handler uses a "security." prefix and allows for per-module
attribute names. Security checking for userspace access to these attributes
can be performed by the security module using the LSM hooks in fs/xattr.c,
and the security module is free to internally use the inode operations
without restriction for managing its security labels. Unlike the trusted
namespace, these labels are used internally for access control purposes by
the security modules, and controls over userspace access to them require
finer granularity than capable() supports.

the taking the inode semaphore so that atomicity is provided for the
security check and the update to the inode security structure.

[PATCH] rationalize scsi_queue_next & friends
(1) second arg to scsi_queue_next_request() is only ever non-NULL
inside scsi_lib.c and only used in the first conditional inside
that function - ripped out of scsi_queue_next_request() and
put into a new helper scsi_requeue_command().
(2) Most remaining callers of are in the form
scsi_put_command(cmd);
scsi_queue_next_request(q, NULL);
add a new helper, scsi_next_command() for them.
(2b) many callers of that still contain a repeated codepath, namely
everything from scsi_release_request except the final kfree.
New helper __scsi_release_request() for those.
(3) All remaining callers loop over the devices of a host and call
scsi_queue_next_request() on them - new helper
scsi_run_host_queues().
(4) scsi_queue_next_request() renamed to scsi_run_queue(), second
arg is gone and it's static to scsi_lib.c now.

[PATCH] USB Gadget API (1/6)

There's additional kerneldoc, which I won't submit at
this time, available.
<david-b@pacbell.net>
[PATCH] Net2280 driver (2/6)
This patch creates drivers/usb/gadget/net2280.[hc],
providing a driver for NetChip's "Net2280 PCI USB 2.0
High Speed Peripheral Controller".
It implements the API included in the first patch.
The driver has behaved well with chiprev 0100 under
stress tests with Gadget Zero and the ethernet model
driver, and has passed sanity tests for chiprev 0110.
<david-b@pacbell.net>
[PATCH] USB "Gadget Zero" driver (3/6)
This patch adds "Gadget Zero" (drivers/usb/gadget/zero.c).
Gadget Zero is a simple gadget driver that's useful for
testing controller drivers, and as an example to be used
for clone/modify style development.
This driver implements two configurations, and needs only
two bulk endpoints (in addition to ep0) ... so pretty much
any USB device controller should be usable with it in
one configuration or another. It (optionally) supports
high speed devices, and has passed the USB-IF "chapter 9"
device model conformance tests.
It's worth noticing the kinds of hardware differences that
gadget drivers need to cope with. Endpoints differ, in
ways that must be reflected various ways in descriptors.
And sometimes chip errata cause interoperability problems;
for example, an sa1100 can't change configurations after
enumerating.
<david-b@pacbell.net>
[PATCH] USB Ethernet Gadget (4/6)
This patch adds an "Ethernet Gadget" driver, implementing
the CDC Ethernet model (drivers/usb/gadget/ether.c).
It interops with the current CDC Ether drivers on Linux,
both 2.4 (CDCEther, using Marcelo's latest) and 2.5
(cdc-ether with recent patches, or on 2.5.68 "usbnet")
On a net2280, this has successfully streamed dozens of
megabytes per second using "ttcp" (high speed, and using
"usbnet" on the host side), for days at a time. And no
problems using SSH/NFS/etc in lighter duty testing.
It's possible this will need tweaking to cope with UDC
bugs on Intel's pxa25x controllers, presenting itself
as a non-CDC device. (I'm told altsettings are even
more broken than originally specified to be.)
<david-b@pacbell.net>
[PATCH] USB Gadget string utility (5/6)
This adds utility code that gadget drivers can use to manage

Both "Gadget Zero" and the Ethernet gadget code use this.

[PATCH] kbuild/kbuild for USB Gadgets (6/6)

just now means net2280, but sa11x0 and pxa25x options
are just waiting for updates!), gadget driver options
are also available.

[PATCH] USB gadget: net2280: dmachain off, zlp pio ok

in-tree drivers seem fine with it.) So disable
for now; it's easily enabled if needed.
- Zero Length Packets (ZLPs):
* Should now read/write ok with PIO.
* On DMA endpoints, explicit ZLPs need PIO.
Until they do, don't allow queuing zero length
buffers onto DMA endpoints.

[PATCH] I2C: Another it87 patch.
This is against my last.
While the old code most definitely did /something/ to the register for
setting the fan div, the 'what' is a more interesting question.
To be honest I could not figure out what it was trying to do, because
the way it was inserting values disagreed with not only the data sheet,
but how it parsed the very same register.
This corrects the issue, and allows one to properly control the divisor
on all 3 fans, including the (much more limited) 3rd fan.
<warp@mercury.d2dc.net>
[PATCH] I2C: Yet another it87 patch.
Ok, after writing up something in the way of a perl script to make some
sense of the data for voltages, and finding that there is no sense to
make, I took a longer look at things.
The it87 driver in 2.5.x is doing some, down right /odd/ math on the
numbers for the in_input* readings, and the 2.4.x driver is doing
something quite different.
And while it might be possible to get sane numbers out of the 2.5.x
driver, people /expect/ to get the numbers that they were getting from
2.4.x.
So this patch puts things back to the simpler calculations done by the
2.4.x lm-sensors drivers, and my script confirms that the numbers come
out right.
<warp@mercury.d2dc.net>
[PATCH] I2C: And another it87 patch.
Don't provide min/max for in8, which allowed one to scribble on
registers one should not be messing with. (My fault, oops.)
The setting of the temp high/low registers was off by one, not mine this
time. While I was at it, I reordered a few other register accesses to
be base 0 instead of base 1.
The temp interface was slightly incorrect, degrees * 100 instead of
degrees * 1000, also fixed.
And lastly, when changing the fan count divisor, fix up the min setting
to still be roughly the same. (Previously the meaning of the value in
the register changed, but not the value itself, resulting in, undesired
surprises.)

[PATCH] Fix potential runqueue deadlock
send_sig_info() has been broken since 2.5.60.
The function can be invoked from a the time interrupt (timer_interrpt ->
do_timer -> update_process_times -> -> update_one_process -> (
do_process_times, do_it_prof, do_it_virt ) -> -> send_sig ->
send_sig_info) but it uses spin_unlock_irq instead of the correct
spin_unlock_irqrestore.
This enables interrupts, and later scheduler_tick() locks runqueue
(without disabling interrupts). And if we are unlucky, a new interrupt
comes at this point. And if this interrupt tries to do wake_up() (like
RTC interrupt does), we will deadlock on runqueue lock :-(
The bug was introduced by signal-fixes-2.5.59-A4, which split the
original send_sig_info into two functions, and in one branch it started
using these unsafe spinlock variants (while the "group" variant uses
irqsave/restore correctly).

This problem was reported against 2.4 by Eddie.Williams@SteelEye.com
There's a problem in the sd spinup code in that if the unit returns NOT
READY, we begin to spin it up, but thereafter if it returns anything
other than NOT READY or success, the while loop in the spinup code will
be executed *without* the 1s delay that's in the NOT READY case.
The problem was seen with a real device: Compaq multi-path storage
arrays return NOT READY to probes down inactive paths, but when the
start unit is sent to activate the path, they can then respond back with
error conditions.
The fix is to terminate the while loop for any unexpected return.

[PATCH] scsi_report_device_reset
aic7xxx/79xx wants a variant of scsi_report_bus_reset that operates
only on a single device. Implement it to get rid of shost->my_devices
traversals in drivers. (and move both to scsi_error.c)

[PATCH] consolidate devlist handling in a single file
Currently it's spread all over the scsi midlayer but having this
nicely separate out to a file of it's own without exposing the
data structures sounds like a good idea.

[PATCH] bio_endio() increments bio->bi_sector
increment bi_sector in bio_endio() so make_request_fn drivers don't
have to do this accounting themselves.

[PATCH] make MO drive work with ide-floppy/ide-cd
Resend of the ide-cd buggy debug check removal.
From der.eremit@email.de.

[PATCH] shrink deadline hash size
Limit deadline hash to 32 entries instead of 1024. This has been benched
and profiled extensively and shows no increased system time.
Also, move "hot" entries to the front of the list.
<axboe@suse.de>
[PATCH] dynamic request allocation
This patch adds dynamic allocation of request structures. Right now we
are reserving 256 requests per initialized queue, which adds up to quite
a lot of memory for even a modest number of queues. For the quoted 4000
disk systems, it's a disaster.
Instead, we mempool 4 requests per queue and put an upper limit on the
number of requests that we will put in-flight as well. I've kept the 128
read/write max in-flight limit for now. It is trivial to experiement
with larger queue sizes now, but I want to change one thing at the time
(the truncate scenario doesn't look all that good with a huge number of
requests, for instance).
Patch has been in -mm for a while, I'm running it here against stock 2.5
as well. Additionally, it actually kills quite a bit of code as well

[PATCH] Correct typo in linux/scsi/scsi.h and introduce new
I notice we seem to have a typo in the SAM_ status codes (they say
IMMEDIATE where they mean INTERMEDIATE).
I've also introduced a new macro who's job is to return true if any of
the possible good return codes is found. This means
SAM_STAT_GOOD
SAM_STAT_INTERMEDIATE
SAM_STAT_INTERMEDIATE_CONDITION_MET
and for now
SAM_STAT_COMMAND_TERMINATED
By and large, this is currently irrelevant to us, since we don't use
linked commands and I've never met a device using COMMAND TERMINATED,
but it may help us in the future.

[PATCH] switch sb1000 to new style net init & pnp
This cleans up the driver big time and gets rid of a big ugly wart
in setup.c. Note that I don't have the hardware so this is only
compile-tested.

[PATCH] irq fixes for wavelan_cs/netwave_cs
This patch for 2.5.68-bk11 will fix the irq handler of some
obsolete wireless drivers (wavelan, wavelan_cs and netwave_cs) plus
assorted fixes. All those drivers have been tested on a SMP box.
<jt@bougret.hpl.hp.com>
[PATCH] Wireless Extension 16
This patch for 2.5.68-bk11 will update Wireless Extension to
version 16 :
o increase bitrate and frequency number for 802.11g/802.11a
o enhanced iwspy support
o minor tweaks and cleanups
This patch is only for the core of WE. The patches for the
individual drivers have been sent to their respective maintainers.
Compared to the previous version I sent you a few weeks ago,
I've just updated to the latest kernel.

[PATCH] WE-16 for Wavelan ISA driver
This update the Wavelan ISA driver for Wireless Extension 16
(going with my previous patch).
<jt@bougret.hpl.hp.com>
[PATCH] WE-16 for Wavelan Pcmcia driver
This patch update the Wavelan Pcmcia driver for Wireless
Extensions 16, and also remove all the backward compatibility cruft
that is broken anyway.
<paulus@samba.org>
[PATCH] Update mac ethernet drivers
This patch updates the bmac and mace ethernet drivers so that their
interrupt routines return an irqreturn_t, and updates the bmac driver
to use a spinlock rather than global cli/sti.
<dean@arctic.org>
[PATCH] better ali1563 integrated ethernet support
it turns out the tulip driver is a much better driver for the integrated
ali1563 ethernet than the dmfe driver... the dmfe driver gets tx timeouts
every ~15s and can't receive over 5MB/s. but with the small tulip patch
below i'm seeing 11MB/s+ in both directions without problems.
<mzyngier@freesurf.fr>
[PATCH] depca update (was Re: [Patch] DMA mapping API for Alpha)
this patch has been sleeping
in Alan tree for quite some time. It updates the depca driver to the
EISA/sysfs API, gets rid of check_region, and properly reserve memory
region. Patch is against latest BK.
<jgarzik@redhat.com>
[bk] add useful tip to bk kernel howto
Kudos to Wayne Scott @ BitMover for this.
<mikpe@csd.uu.se>
[PATCH] restore sysenter MSRs at APM resume
This changes apm.c to invoke suspend.c's save and restore processor
state procedures around suspends, which fixes the SYSENTER MSR problem.
The patch also decouples sysenter.c from SOFTWARE_SUSPEND: the variables
used (only!) in suspend_asm.S are moved there, and the include file now
declares the procedures called from apm.c (previously they were only
called from suspend_asm.S).

[PATCH] fix lost IDE interrupt problem
Alan and I were investigating this, but we don't know why the problem
occurs.
This reverts the previous handling of masked_irq, and fixes the problem.

[PATCH] more kbuild tweaks]
This fixes a typo reported by Geert, and more significantly
fixes static linking so that it works even when only the
device side of USB is enabled, and the host side (CONFIG_USB)
isn't.
<david-b@pacbell.net>
[PATCH] Fix big-endian USB gadget build
Initializers must be constant expressions, and thus we can't use the
complex expression "cpu_to_le*()" - the end result of which may have a
constant _value_ but the expression itself isn't a constant expression.
So use the explicitly constant "__constant_cpu_to_*()" expression
instead.

[PATCH] two more templates in headers
I missed aic7xxx_old and cciss_scsi. For the first it's the trivial
move, for the second it's the patch to move to scsi_add_host & friend
as already ACKed by Steve when he still was cciss maintainer.
<bgerst@didntduck.org>
[PATCH] Fix ioperm bitmap
This makes sure that the ioperm bitmap in the TSS is correctly set up
during the first ioperm() call. Without this the TSS bitmap contains
random garbage until the next context switch.

ACPI: kobject fix (Greg KH)
Here's a small patch that fixes the logic of the kobject creation and
registration in the acpi code (since we use kobject_init(), we need to
use kobject_add(), not kobject_register() to add the kobject to the
kernel systems).
<agrover@groveronline.com>
ACPI: Allow ":" in OS override string (Ducrot Bruno)
<agrover@groveronline.com>
ACPI: Interpreter update to 20030509
Changed the subsystem initialization sequence to hold off installation of
address space handlers until the hardware has been initialized and the
system has entered ACPI mode. This is because the installation of space
handlers can cause _REG methods to be run. Previously, the _REG methods
could potentially be run before ACPI mode was enabled.
