Summary of changes from v2.5.64 to v2.5.65
============================================
<sds@epoch.ncsc.mil>
[PATCH] Add LSM hook to do_kern_mount
This patch adds a security_sb_kern_mount hook call to the do_kern_mount
function. This hook enables initialization of the superblock security
information of all superblock objects. Placing a hook in do_kern_mount
was originally suggested by Al Viro. This hook is used by SELinux to
setup the superblock security state and eliminated the need for the
superblock_precondition function.
<sds@epoch.ncsc.mil>
[PATCH] Replace inode_post_lookup hook with d_instantiate hook
This patch removes the security_inode_post_lookup hook entirely and
adds a security_d_instantiate hook call to the d_instantiate function
and the d_splice_alias function. The inode_post_lookup hook was
subject to races since the inode is already accessible through the
dcache before it is called, didn't handle filesystems that directly
populate the dcache, and wasn't always called in the desired context
(e.g. for pipe, shmem, and devpts inodes). The d_instantiate hook
enables initialization of the inode security information. This hook
is used by SELinux and by DTE to setup the inode security state, and
eliminated the need for the inode_precondition function in SELinux.
<sds@epoch.ncsc.mil>
[PATCH] allocate and free security structures for private files
This patch adds a security_file_alloc call to init_private_file and
creates a close_private_file function to encapsulate the release of
private file structures. These changes ensure that security
structures for private files will be allocated and freed
appropriately. Per Andi Kleen's comments, the patch also renames
init_private_file to open_private_file to force updating of all
callers, since they will also need to be updated to use
close_private_file to avoid a leak of the security structure. Per
Christoph Hellwig's comments, the patch also replaces the 'mode'
argument with a 'flags' argument, computing the f_mode from the flags,
and it explicitly tests f_op prior to dereferencing, as in
dentry_open().
<sds@epoch.ncsc.mil>
[PATCH] Restore LSM hook calls to setpriority and setpgid
This patch restores the LSM hook calls in setpriority and setpgid to
2.5.58. These hooks were previously added as of 2.5.27, but the hook
calls were subsequently lost as a result of other changes to the code
as of 2.5.37.
Ingo has signed off on this patch, and no one else has objected.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Fix up missed return value
Spotted by Joe Perches.
<sds@epoch.ncsc.mil>
[PATCH] LSM: Add LSM sysctl hook to 2.5.59
This patch adds a LSM sysctl hook for controlling access to
sysctl variables to 2.5.59, split out from the lsm-2.5 BitKeeper tree.
SELinux uses this hook to control such accesses in accordance with the
security policy configuration.
<sds@epoch.ncsc.mil>
[PATCH] LSM: Add LSM syslog hook to 2.5.59
This patch adds the LSM security_syslog hook for controlling the
syslog(2) interface relative to 2.5.59 plus the previously posted
security_sysctl patch. In response to earlier comments by Christoph,
the existing capability check for syslog(2) is moved into the
capability security module hook function, and a corresponding dummy
security module hook function is defined that provides traditional
superuser behavior. The LSM hook is placed in do_syslog rather than
sys_syslog so that it is called when either the system call interface
or the /proc/kmsg interface is used. SELinux uses this hook to
control access to the kernel message ring and to the console log
level.

ia64: Minor whitespace & formatting fixups in asm-ia64/sal.h.
<davidm@tiger.hpl.hp.com>
ia64: Minor cleanups.
<davidm@tiger.hpl.hp.com>
ia64: Make signal deliver work when the current register frame is
incomplete (as a result of a faulting mandatory RSE load).
<davidm@tiger.hpl.hp.com>
ia64: Fix typo in #error message of page-fault handler.
<eranian@hpl.hp.com>
[PATCH] ia64: perfmon patch for 2.5.59
Here is the patch that matches the changes I made for RHAS w.r.t
perfmon and the O(1) scheduler. This fixes the deadlocks we were
seing in RHAS and therefore on 2.5 as well.
The key change is that SIGPROF notifications are now delivered
in the perfmon kernel exit handler (called from entry.S).
At that point, we know none of the runqueue locks are held.
I have run the same test suite I used on RHAS overnight and no
sign of deadlocks.
<davidm@tiger.hpl.hp.com>
ia64: Sync up with 2.5.60.
<davidm@tiger.hpl.hp.com>
ia64: Fix do_gettimeoffset() to not update last_nsec_offset with (potentially)
invalid values.
<sds@epoch.ncsc.mil>
[PATCH] LSM: coding style fixups in sb_kern_mount
This patch moves the error handling code for the sb_kern_mount hook call
out of line, per Christoph Hellwig's suggestion.
<greg@kroah.com>
LSM: fix merge where we lost a prototype in security.h
<kai@vaio.(none)>
ISDN: Resolve name clash in hisax
isac_setup() was defined in two different modules and so clashed
with everything compiled into the kernel. The proper fix would
be to rather kill one of the duplicate drivers, but for now just
rename one symbol.
<kai@vaio.(none)>
ISDN/HiSax: Fix some warnings
gcc 3.2 is asking for a little more const correctness...
<kai@vaio.(none)>
ISDN: [PATCH] isdn_net_lib.c must include isdn_concap.h
From Adrian Bunk:
> With CONFIG_ISDN_X25 enabled I got the following compile error in
> isdn_net_lib.c in 2.5.61:
> The following patch solved it for me:
Additionally, disable CONFIG_ISDN_X25 in Kconfig, since it's still
badly broken.
<kai@vaio.(none)>
ISDN/AVMB1: Fix compile w/o CONFIG_ISDN_DRV_AVMB1_B1PCIV4
<kai@vaio.(none)>
ISDN: Fix compile error w/o CONFIG_ISDN_PPP_MP
The proto argument is not used, so just remove it from ippp*_xmit()
calls - in particular we passed it to ippp_xmit() when
CONFIG_ISDN_PPP_MP was off, which never wanted it anyway, causing
a compile error.
<kai@vaio.(none)>
ISDN: Fix hisax_fcpcipnp PnP
Seems the PnP layer changed again, breaking hisax_fcpcipnp.
Fixed again (untested, though).
<anton@samba.org>
ppc64: use fast version of mtmsrd when changing RI, from Milton Miller
<anton@samba.org>
ppc64: remove extra clear of RI, we do it later on, from Milton Miller

<mgreer@mvista.com>
PPC32: Fix our L2 / L3 cache updates for the bootloader.
<louisk@cse.unsw.edu.au>
[PATCH] ia64: fsys-version of gettimeofday()
This version executes in around 300 cycles on Itanium I (down from 900
or so for the original version), and so can be said to have
microsecond precision.
<davidm@tiger.hpl.hp.com>
ia64: Fix fsys_gettimeofday() and tune it some more.
<davidm@tiger.hpl.hp.com>
ia64: Add forgotten probe.w.fault checks in fsys_gettimeofday().

[PATCH] nautilus poweroff
The power management unit on newer 1535D/D+ ALI bridges
(UP1100/UP1500) is quite different to 1543C one on UP1000.
Even though it has the same PCI id and revision number...
This makes poweroff(8) work on UP1100 and UP1500.
Ivan.

[PATCH] ia64: rwsem using atomic primitive
<kaos@sgi.com>
[PATCH] ia64: fix scratch-regs handling in kernel unwinder
This patch has been running inside SGI for 2 months. It
handles kernel stacks with multiple struct pt_regs, as found
while debugging the kernel.
<davidm@tiger.hpl.hp.com>
ia64; Improve debug output from kernel unwinder. Based on patch by
Keith Owens.
<davidm@tiger.hpl.hp.com>
ia64: In kernel unwinder, replace dump_info_pt() with get_scratch_regs()
and reformat to make it fit in 100 columns.
<bjorn_helgaas@hp.com>
[PATCH] ia64: iosapic: make pcat_compat system property
Make pcat_compat a system property, not a per-IOSAPIC property.
<bjorn_helgaas@hp.com>
[PATCH] ia64: iosapic: remove find_iosapic duplication
emove IOSAPIC address and GSI base from external interrupt
registration interfaces. This lets us remove acpi_find_iosapic(),
which is functionally similar to find_iosapic().
<bjorn_helgaas@hp.com>
[PATCH] ia64: iosapic: simplify ISA IRQ init
Simplify ISA IRQ init by taking advantage of iosapic_override_isa_irq(),
which already does what we need.
<bjorn_helgaas@hp.com>
[PATCH] ia64: iosapic: self-documenting polarity/trigger arguments
Make interrupt registration functions take named constants for
polarity and trigger mode. Old -> new magic decoder ring:
polarity 0 -> IOSAPIC_POL_LOW(#defined to 1)
polarity 1 -> IOSAPIC_POL_HIGH(#defined to 0)
trigger 0 -> IOSAPIC_LEVEL(#defined to 1)
trigger 1 -> IOSAPIC_EDGE(#defined to 0)
<bjorn_helgaas@hp.com>
[PATCH] ia64: iosapic: rationalize __init/__devinit
Rationalize __init/__devinit attributes. The noteworthy changes are
that
iosapic_system_init(),
iosapic_init(),
iosapic_register_platform_intr(), and
iosapic_override_isa_irq()
are __init (only called from ACPI __init functions), but
iosapic_lists[],
num_iosapic,
find_iosapic(),
register_intr(),
iosapic_register_intr(), and
acpi_register_irq()
are not because they may be used after init-time by modules.

ia64: Correct region_start calculation in kernel unwinder.
<suresh.b.siddha@intel.com>
[PATCH] ia64: 1/2 fix for generic kernel
Current 2.5 kernels are broken with CONFIG_IA64_GENERIC option. Two unused
members are still remaining in the structure, resulting in corruption of
structure elements during the MACHVEC_INIT initialization. Attached patch
fixes this problem.
<suresh.b.siddha@intel.com>
[PATCH] ia64: 2/2 fix in machvec.h
IA64 ABI specifies that globals > 8 bytes need to be aligned to 16 bytes.
gcc doesn't follow this convention. Current kernel code will fail to work with
a compiler which follows the ABI.
size of structure ia64_machine_vector is > 8 bytes and not multiple of 16 bytes.
When we have CONFIG_IA64_GENERIC, each machine specific vector from different
object files gets linked into a user defined section(forming array of
structures).
Now with a compiler conforming to ABI, there will be holes in this array
resulting in the code failure when it goes through this array of structures.
Following patch will make the size of the structure to be multiple of 16 bytes
making both ABI confirming/non-conforming compilers happy.
<jbarnes@sgi.com>
[PATCH] ia64: SN updates for mmzone.h
Here's an update to the ia64 mmzone.h file that adds some SN2 specific
defines (which will probably have to be changed later, but it's a
start).
<jbarnes@sgi.com>
[PATCH] ia64: SN update
And here's the SN specific part of the update. This should get an SN2
compile all the way to the link stage, where I still have some devfs
stuff to cleanup.
<rohit.seth@intel.com>
[PATCH] ia64: HugeTLB Page patch for IA-64 2.5.60 kernel
Please find attached a hugetlb page patch for IA-64 2.5.60 kernel .
Changes in generic files are mostly backported from 2.5.62 (to get
hugetlb support functioning properly).
<rohit.seth@intel.com>
[PATCH] ia64: 2nd update for HugeTLB Page patch for IA-64 2.5.60 kernel
Please find attached a small hugetlb page support update for 2.5.60
IA-64 kernel (+ my previous hugetlb page patch). This patch adds the
HAVE_ARCH_HUGETLB_UNMAPPED_AREA define for IA-64 arch.
hugetlb_get_unmapped_area function is added in
arch/ia64/mm/hugetlbpage.c
<peter@chubb.wattle.id.au>

Many places use inappropriate types for comparing jiffies,
int for example. Fix those places up.
<davem@nuts.ninka.net>
[SPARC64]: Fix cpufreq config deps.

[PATCH] USB: add support for Treo devices to the visor driver.
Finally...
<clemens@ladisch.de>
[PATCH] usb-midi.h: fixes for SC-8820/50
sync with Nagano's version:
- protect vendors ids against multiple definitions
- sort Roland device ids
- fix SC-8850 cable bitmask
- add quirk for the SC-8820
- add quirk for the MOTU Fastlane
<andre.breiler@null-mx.org>
[PATCH] io_edgeport.c diff to fix endianess bugs
attached a fix for the io_edgeport usb serial driver
This diff fixes endianess issues which prevented the driver to work on
bigendian machines (e.g. sparc).
<andmike@us.ibm.com>
[PATCH] Fix SCSI error handler abort case
I had my list empty checks reversed if aborting and bus device reset
failed. The condition that causes the error handler to run is still
unknown.
<greg@kroah.com>
[PATCH] USB: added support for radio shack device to pl2303 driver.
Thanks to gene_heskett@iolinc.net for the info for this.
<levon@movementarian.org>
[PATCH] Fix oprofile on UP, small additional fix
The below has been in -mm for a while, and has been tested on my UP
and 2-way machines.
OProfile was completely unsafe on UP - a spinlock is no protection
against the NMI arriving and putting data into the buffer. Pretty stupid
bug. This fixes it by implementing reader/writer windows in the buffer
and removing the lock altogether. This patch was originally done by Will
Cohen.
It also fixes the oops Dave Hansen saw on 2.5.62 SMP
<mochel@osdl.org>
sysfs: Make sure root inode is executable and readable by everyone.
<mochel@osdl.org>
driver model: fix platform_match()
- Make it compare the name in struct platform_dev to the driver's name.
From Dominik Brodowski
<mochel@osdl.org>
sysfs: don't complain when sysfs can't register.
During startup, sysfs won't succeed in registering with itself, because
it's not yet inititialized. This was causing an unnecessary error on boot.
<mochel@osdl.org>
cpufreq: fix compile error.
Use ->dev instead of ->intf.dev in struct cpufreq_policy. Introduced whilst
cleaning up part of the cpufreq code.
<miyazawa@linux-ipv6.org>
[IPSEC]: Add full ipv6 support.
Credits also to Mitsuru Kanda <kanda@karaba.org>,
YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>,
and Kunihiro Ishiguro.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Make build stop on vmlinux link error
set -e is needed for each (continued) line.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Add some missing FORCE
Those were missing, not particularly harmful, but still needed for
correctness.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Make per-cpu-check ignore __crc_ symbols.
We warn when symbols end in __per_cpu, but aren't in the per-cpu section.
However, checksum symbols gave false positives.
<sam@mars.ravnborg.org>
[PATCH] kbuild: Smart notation for non-verbose output
Create a nice shorthand to enable the non-verbose output mode.
make V=1 => Gives verbose output (default)
make V=0 => Gives non-verbose output
One of the reasons why people does not use KBUILD_VERBOSE=0 that
much is simply the typing needed.
This notation should make it acceptable to type it.
The usage of "make V=0" is restricted to the command line.
Anyone that wants to enable the non-verbose mode pr. default shall
set KBUILD_VERBOSE in the shell.
<arnd@arndb.de>
[trivial] avoid a warning for each module on s390x
s390x has a reference to _GLOBAL_OFFSET_TABLE_ in each module
that is resolved by the module loader. This patch prevents
modpost from emitting a warning about that symbol.
<sam@mars.ravnborg.org>
[PATCH] kbuild: touch-module after successfull creation only

> scripts/Makefile.modinst:16: *** Uh-oh, you have stale module entries. You

This happens if you have encountered a compile error in a module.
In this case you did not succeed the compilation of fs/binfmt_aout,
and therefore no .o file can be located.
kbuild assumes this is because you have messed with SUBDIRS, which is wrong.

[KERNEL]: Add typecheck macro for verifying types at compile time.
<davem@nuts.ninka.net>
[JIFFIES]: Use typecheck in time_foo jiffies macros.
<torvalds@home.transmeta.com>
Fix up some timeouts to use the proper types.
(While "signed long" is the same in practice, it is technically
incorrect, and the new anal type-checker complains).

[ARM] Remove set_mac_address from acorn drivers.
Acorn Ethernet drivers provided a duplicate set_mac_address
implementation which reflects the generic ethernet version in
drivers/net/net_init.c. Use the generic version instead.
<rmk@flint.arm.linux.org.uk>
[ARM] Convert ecard.c shutdown/reboot to use driver model
ecard.c used to use the reboot notifier to ensure that the expansion

<rmk@flint.arm.linux.org.uk>
[ARM] Ensure we preserve other CPSR bits when switching to SVC mode.
<rmk@flint.arm.linux.org.uk>
[ARM] Power management updates
This provides an element of core PM support to ARM, providing an APM
like user space interface, and separating the core PM support from
the SA1100 PM implementation.
<rmk@flint.arm.linux.org.uk>
[ARM] Add better PM support to SA1111 and SA11x0.
This follows our existing PM interfaces.

[CPUFREQ] Update ARM CPUFREQ drivers
A 4 patch set from Dominik Brodowski, tested and fixed up by rmk
for ARM.
(1)
- the system3.c cpufreq notifier couldn't possibly compile before because
cpufreq_updateminmax has been undefined for ages.
- clean up sa1100fb.c notifier to specify exactly what's left TBD.
- double #include of cpufreq.c in drivers/pcmcia/sa1100_generic.c
(2)
Split up config symbols, add help text for CPU_FREQ_PROC_INTF
(3)
- update the Integrator CPUfreq driver so that it can get along with
cpufreq policies.
- modularize Integrator CPUfreq driver (all it did with
!CONFIG_CPU_FREQ was to print out some debug information)
(4)
- update the SA11x0 CPUfreq drivers so that they can get along with
cpufreq policies and governors.
- update the cpufreq core so that cpufreq_get() returns something
sensible during the first ->setpolicy or ->target call.

[CPUFREQ] Make sa11x0_ppcr_to_freq return in units of kHz, not 100kHz.
<torvalds@home.transmeta.com>
Make the "interactive bonus" work both ways - both the process
that is actually showing interactive behaviour (sleeping) and the
process that wakes up the interative process get a bonus.
This means that processes that help interactive processes (usually
system daemons, and X11 in particular) will themselves get some bonus.
The waker only gets whatever is left over from the "real" interactive
user, to avoid any bad behaviour.
<mingo@elte.hu>
[PATCH] "interactivity changes", sched-2.5.64-A6
This includes the following items:
- a new wakeup feature: SMART_WAKE_CHILD (now unconditional) [this is a
reworked version of the wakeup changes from Andrea's tree.]
- scheduler parameter tunings (CHILD_PENALTY, MAX_TIMESLICE,
STARVATION_LIMIT, MAX_SLEEP_AVG)
- activate_task() splitup to separate the interactivity-active variant
from the task-queue variant => this fixes our statistics in some cases.
- finer-grained preemption: if priority is equal then the task with the
longer pending timeslice wins.
- make it possible to disable sync-wakeups via SYNC_WAKEUPS (default:1)
- a naming cleanup (sleep_timestamp => last_run)
- fix up STARVATION_LIMIT usage so that a value of 0 is recognized as 'no
starvation limit'.
It also merges Linus' "priority boost backmerging"

[PATCH] USB: track usb ch9 device state
This patch merges the USB state definitions from the ARM Linux
code (inside the sa1100 driver) and uses them to track what can
be done with the device. That replaces the recently added
"udev->present" flag with a more complete/standard state model.
There are a few changes that might affect behavior if things
start to go really haywire:
- usb_set_address() and usb_set_configuration(), used while
enumerating, handle some unlikely cases more correctly:
don't allow setting address to zero (undefined behavior),
and do allow un-configuring (config 0). (Adds a FIXME
for an existing set-configuration bug too.)
- usb_disconnect() flags the state change earlier (as soon
as it's known).
- usb_submit_urb() works in the states where messaging is
allowed, and also enforces the "unless configured, only
control traffic is legal" rule.
- usb_unlink_urb() doesn't care any more about that state.
(There seemed to be agreement that it must not matter.)
This will help with some further cleanups in the complex of
issues relating to driver removal, device removal, config
changing (with driver unbind and rebind), reset, and so on.
<greg@kroah.com>
[PATCH] USB: unfortunatly, we can't call usb_unlink_urb() right now all of the time.

[PATCH] remove __pgd_offset
Patch from Dave Hansen <haveblue@us.ibm.com>
__pgd_offset() and pgd_offset() are completely different functions.
__pgd_offset() is really just a helper to figure out which entry in a
pgd an address would fall into. pgd_offset() does all the leg work and
actually fetches the real pgd entry.
pgd_index() is a much saner name for what __pgd_offset() does. In fact,
we do this:
#define __pgd_offset(address) pgd_index(address)
The attached patch removes all instances of __pgd_offset and just
replaces them with pgd_index.
Compiles with and without PAE on x86.

[PATCH] scsi_error fix
imm.c: spelling
scsi.h: remove old and now incorrect comment
scsi_scan.c: remove superfluous final return
scsi_error.c: apart from similar trivialities the only change:
If a command fails (e.g. because it belongs to a newer
SCSI version than the device), it is fed to
scsi_decide_disposition(). That routine must return
SUCCESS, unless the error handler should be invoked.
In the situation where host_byte is DID_OK, and message_byte
is COMMAND_COMPLETE, and status is CHECK_CONDITION, there is
no reason at all to invoke aborts and resets. The situation
is normal. I see here UNIT ATTENTION, Power on occurred
and ILLEGAL REQUEST, Invalid field in cdb.
The 2.5.64 code does not return SUCCESS, but it returns the
return code of scsi_check_sense(), and that may be FAILED
in case we do not have valid sense.

<rmk@arm.linux.org.uk>
[PATCH] Eliminate stack allocation of struct pci_dev...
- Eliminate the stack allocation of a struct pci_dev, and make
pci_scan_slot() take a bus and a devfn argument.
- Add "dev->multifunction" to indicate whether this is a multifunction
device.
- Run header fixups before inserting the new pci device into any
device lists or announcing it to the drivers.
- Convert some more stuff to use the list_for_each* macro(s).
<rmk@arm.linux.org.uk>
[PATCH] Only add devices to bus->devices while scanning...
The pci_find* functions search using the following lists:
bus->children (for subordinate buses)
pci_root_buses (for all root buses)
pci_devices (for devices)
This leaves one list which we can add devices to without any drivers
finding the new devices before we've finished with them.
- initialise bus->node list head.
- pci_scan_slot will scan the specified slot, and add the discovered
devices to the bus->devices list only. These devices will not
appear on the global device list, and do not show in sysfs, procfs.
pci_scan_slot returns the number of functions found. If you want
to find the devices, you have to scan bus->devices and look for
devices where list_empty(&dev->global_list) is true.
- new function "pci_bus_add_devices" adds newly discovered devices
to the global device lists, and handles the sysfs and procfs
stuff, making the devices available to drivers. All our buses
which have an empty list head are treated as "new" (since they
are not attached to the parent buses list of children) and are
also added. Currently, no buses will be in this state when this
function is called.
- new function "pci_scan_child_bus" scans a complete bus, building
a list of devices on bus->devices only, performing bus fixups
via pcibios_fixup_bus() and scanning behind bridges. It does
make devices externally visible.
- pci_do_scan_bus retains its original behaviour - ie, it scans
and makes devices available immediately.
<rmk@arm.linux.org.uk>
[PATCH] Convert setup-bus resource allocation to use bus->devices
- Convert setup-bus.c resource allocation to scan bus->devices rather
than bus->children. As noted previously, newly discovered child
buses will not be on the parents list of children buses, so when
we're trying to assign resources, we need to scan the bus for
devices with subordinate buses rather than using the list of children
buses.
<rmk@arm.linux.org.uk>
[PATCH] Fix up pci_scan_bridge and friends
Now we tackle pci_add_new_bus and pci_scan_bridge. The hotplug code
currently uses this, but I'd like it to die off; pci_scan_bridge()
should be used to scan behind bridges. This may mean hotplug needs
some changes to pci_scan_bridge - if so, we need to find out what
changes are required and fix it.
pci_alloc_child_bus() does what pci_add_new_bus() did, except it
doesn't attach the new bus to the parents list of child buses. The
only way this bus can be reached from the parent bus is by scanning
the parents devices list, and locating a device with a non-NULL
subordinate bus. The only code which should be doing this is the
PCI code.
Since the new bus will have an empty list head for bus->node, we can
detect unattached buses prety easily. (see pci-3.diff.)
pci_scan_bridge() changes slightly - we use our new pci_scan_child_bus()
function from pci-3.diff, which doesn't attach devices to the global
tree. This means callers of pci_scan_child_bus() and pci_scan_bridge()
(ie, hotplug) will need to call pci_bus_add_devices().
<hpa@transmeta.com>
[PATCH] bootsect removal
This is the "boot sector removal" patch for i386 updated for Linux
2.5.63-bk7. The only change against the 2.5.59 version is that the
FDOPTS Makefile variable, which lets one create a floppy image with
arbitrary kernel options, has been merged from the x86-64 version, and
the comments have been updated.
The patch removes the in-kernel boot sector, which these days rarely
work correctly (it only supports up to 1 MB kernels, and only work on
legacy floppies -- not on IDE or USB devices, nor on any kind of
emulated devices like El Torito), replaces it with a placeholder stub,
and sets up the Makefile targets to create floppies or floppy images
using SYSLINUX. The FDOPTS Makefile variable can be used to set
kernel command line options (thanks to a suggestion by Andi Kleen.)
Note that the same change has already been applied to the x86-64
architecture. The last hunk of the patch corrects a comment in that
architecture.

[PATCH] more "interactivity changes", sched-B2
- fix a (now-) bug in kernel/softirq.c, it did a wakeup outside any

distributed.
- reset the initial idle thread's priority back to PRIO_MAX after doing
the wakeup_forked_process() - correct preemption relies on this.
- update current->prio immediately after a backboost.
- clean up effective_prio() & sleep_avg calculations so that there are
fewer RT-task special cases. This has the advantage of the sleep_avg
being maintained even for RT tasks - this could be advantegous for
tasks that briefly enter/exit RT mode.

<mingo@elte.hu>
[PATCH] "interactivity changes", sched-2.5.64-B2
This fixes the SMP runqueue locking bug when updating the wakers
priority. It also includes:
- only update the priority and do a requeueing if the sleep average has
changed. (this does not happen for pure CPU hogs or pure interactive
tasks, so no need to requeue/recalc-prio in that case.) [All the
necessary values are available at that point already, so gcc should
have an easy job making this branch really cheap.]
- do not do a full task activation in the migration-thread path - that is
supposed to be near-atomic anyway.
- fix up comments
I solved the SMP locking bug by moving the requeueing outside of
try_to_wake_up(). It does not matter that the priority update is not
atomically done now, since the current process wont do anything
inbetween. (well, it could get preempted in a preemptible kernel, but
even that wont do any harm.)

kbuild: Do not clutter output with make -jN
Added a new rule filechk used to check when a generated file
actually is changed. If there is no actual changes the file
is left without updating the timestamp.
When building a kernel from scratch two printouts occurs:
CHK file-to-generate
UPD file-to-generate
The first line tell that kbuild checks the file, second line tell that
the file is being updated (or created).
On successive runs only the first line is printed.
Output is the same in verbose and non-verbose mode.
This replaces the former update-if-changed which has been deleted.
generate-asm-offsets.h has been renamed as well.
All users are updated in next patch.
Output when generating compile.h follow above style

[CPUFREQ] fix cpufreq core breakage(s)
- update two more cpufreq-related sysfs files to the new interface
code
- always store the new, user-requested policy in another struct
cpufreq_policy so that we can safely fall back to the old one in
case something fails (this equals the behaviour before Pat's patch)
- the kobject which was registered in cpufreq_add_dev was inside a variable
private to this function -- so the whole cpufreq sysfs interface returned
-EINVAL.

[CPUFREQ] fix userspace governor.

[CPUFREQ] remove unneeded code
- no cpufreq driver uses the frequency table helper "setpolicy" any more
("target" is much more appropriate for them anyways) - so remove

- all cpufreq drivers use the advanced registration process, so some
compatibility code can safely be removed.
<davej@codemonkey.org.uk>
[CPUFREQ] updated cpufreq ref-counting and locking scheme
This patch takes use of the now-working cpufreq_interface.kset and
cpufreq_policy.kobj to use reference counting within the cpufreq core
wherever this is more appropriate than the previous approach -- using one
semaphore. Additionally, the callbacks to the driver modules are protected
now.

[PATCH] no need for kernel_flag on UP

[SERIAL] Overhaul 8250_pci.c
- Add local copy of flags for describing port characteristics.
- Add "quirk" handling to sort out board-specific initialisation,
per-port setup, and finalisation.
- Remove quirk information from struct pci_board array, thereby
making entries more generic.
- Initialise struct pci_board array using explicit indicies -
adding to the readability, and making sure that the right entries
are in the correct location in the table.
- Ensure we tell the serial layer to claim resources, and share
interrupts. PCI interrupts are sharable, and need to be so that
multi-function cardbus cards will work.
- Only remap each PCI memory BAR once.
- Add pci serial driver to the tty devclass (this requires the patch
to make tty_io.c register the tty devclass early.)
Tested by CaT and myself.

[PATCH] register_blkdev cleanups
Patch from Andries.Brouwer@cwi.nl
The following patch does the following:
- static const char *blkdevs[MAX_BLKDEV]; disappears
- get_blkdev_list, (un)register_blkdev, __bdevname
are moved from block_dev.c to genhd.c
- the third "fops" parameter of register_blkdev was unused;
now removed everywhere
- zillions of places had printk("cannot get major") upon
error return from register_blkdev; removed all of these
and inserted a single printk in register_blkdev.
Of course the reason for the patch is that one fixed size
array is eliminated.
<akpm@digeo.com>
[PATCH] fix possible latency in balance_dirty_pages()
Tasks which throttle in balance_dirty_pages() will loop until the amount of
dirty memory falls below the configured dirty_ratio.
This exposes the possibility that one task could be stuck in there for
arbitrary periods of time due to page dirtying activity by other tasks.
The patch changes the logic so that tasks will break out of the loop if they
have written enough pages, regardless of the current dirty memory limits.
Here "enough" pages is 1.5x the number of pages which they just dirtied.
If the amount of dirty memory in the machine happens to still exceed
dirty_ratio (say, due to MAP_SHARED activity) then the task will again
throttle after dirtying a single page. But there is now an upper limit on
the time for which a single task will be captured in balance_dirty_pages().

Some workloads really, really want to have no readahead. Databases which are

do not start it again until we have seen max_readahead()'s worth of
consecutive reads.

[PATCH] hugetlb unmap_vmas() SMP && PREEMPT fix
Patch from Kevin Pedretti <pedretti@ieee.org>
The unmap_vmas() logic is designed to chew away at all the pages without
holding off preemption for too long. But with CONFIG_SMP=y and
CONFIG_PREEMPT=y the number of pages which we batch up between rescheduling
opportunities is not a multiple of HPAGE_SIZE. So unmap_vmas() ends up
calling unmap_hugepage_range() with a poorly aligned&sized region, and it
goes BUG.
Fix that up by ensuring that we always work across hugepage regions in
HPAGE_SIZE chunks.

[PATCH] Extended attribute sharing and debug macro typo fixes
Patch from Andreas Gruenbacher <agruen@suse.de>
Tony Dziedzic has found two bugs in the extended attributes code. Patches with
explanations are attached.
1: Extended attribute sharing on ext2/ext3 not working
The mb_cache_entry_insert function constantly returns an -EBUSY error
instead of 0, which causes the xattr cache that is needed by the xattr
sharing mechanism on ext2/ext3 to not share anything. This patch fixes
the problem. (It is possible that after applying this fix we will hit
bugs in code that wasn't used before.)
2: Oops in one of the xattr debug statements: The old_bh variable is NULL
if an inode that previously had no EA's assigned would share an EA block
with another inode. (This was hidden by the xattr sharing bug).

[PATCH] protect 'action' in show_interrupts

[PATCH] fix SMP lockup in eepro100 with ethtool on unused
Patch from Jason Lunz <lunz@falooley.org>
When support for the GSET and SSET ethtool ioctls was added to eepro100.c in
2.4.20, the tx lock was overloaded to serialize their use. Unfortunately,
this lock is only initialized in dev->open(), causing ethtool to deadlock the
machine when used on an unconfigured eepro100 interface.
The fix is to initialize the spinlock at probe time.

[PATCH] raw.c: dev_t cleanup and oops fix
Patch from Andries.Brouwer@cwi.nl
The next patch in the dev_t series eliminates the last applied use
of MAX_BLKDEV - only the definition in major.h remains.
Sneaky as I am, I combine this patch with the fix for an Oops:
On open, raw_open does
filp->f_dentry->d_inode->i_mapping =
bdev->bd_inode->i_mapping;
storing a pointer to bdev stuff.
But on release this pointer stayed, the block device is not
referenced anymore and disappears, and the next open references
undefined stuff.
I checked, and this can actually cause an Oops - scenario:
# raw /dev/raw/raw12 /dev/hdf
# dd if=/dev/raw/raw12 of=/dev/null bs=512 count=1
# raw /dev/raw/raw12 0 0
# dd if=/dev/raw/raw12 of=/dev/null bs=512 count=1
Oops.
More precisely the problem is that dentry_open does
file_ra_state_init(&f->f_ra, inode->i_mapping);
And file_ra_state_init uses mapping->backing_dev_info->ra_pages.
Ugly, to use so much information about the inode even before
the inode has been opened.
In the patch below I reset i_mapping upon release of the raw device.
akpm: I fixed a typo and exported default_backing_dev_info to GPL modules for
this.

[PATCH] revert the "remove kernel_flag" patch
With CONFIG_SMP=n, CONFIG_PREEMPT=y, CONFIG_DEBUG_SPINLOCK=y we get many

This is because spinlock debugging works on uniprocessor kernels now, and it
stores state inside the spinlock structure to do this.

saving four bytes, so...

<ak@muc.de>
[PATCH] Fast path context switch - microoptimize FPU reload
Following some changes on x86-64.
When cpu_has_fxsr is defined to 1 like in many kernels unlazy_fpu can
collapse to three instructions. For that inlining is a very good idea.
Otherwise it's 10 instructions or so, which can be still inlined.
We don't need the lock prefix to test our local thread flags state.
Unfortunately test_thread_flag currently always uses test_bit which
has a LOCK on SMP, but that's unnecessary. LOCK is costly on P4,
so it's a good idea to avoid it.
Work around this for now by testing directly. Better would be
probably to define __set_bit for all architectures to not guarantee
atomicity and then always use that for local thread_info accesses
in linux/thread_info.h

kbuild: Use targets := to tell kbuild about additional targets
EXTRA_TARGETS served several purposes before:
1) List targets to be build (built-in only)
2) Inform kbuild of targets within the makefile
Mixing the above are causing confusion, so for now on
targets :=
is used to inform kbuild about targets in a Makefile - that it otherwise
did not know about.
kbuild uses the "targets :=" information to:
a) read the dependency file .target.cmd
b) delete the target file during make clean

Move "used FPU status" into new non-atomic thread_info->status field.

status setting, since we don't have to worry about other CPU's racing
on the fields.
Also, fix x86 FP state after fork() by making sure the FP is unlazied
_before_ we copy the state information. Otherwise, if a process did a
fork() while holding the FP state lazily in the registers, the child
would incorrectly unlazy bogus state.

JFS: Fix hang while flushing outstanding transactions under heavy load
During syncbarrier recovery, when JFS is waiting for all outstanding
transactions to complete before allowing new ones to start, there was a
window where a new transaction starts, but is not committed when JFS thought
it could stop flushing the journal to disk. This caused the log_SYNCBARRIER
flag to not be reset, and no new transactions are allowed to start.
This is fixed by using the log->active field to determine when to reset the
log_FLUSH flag.

Use a fixed per-cpu SYSENTER_MSR_ESP value by having the sysenter
entry routine load the real ESP0 off that per-cpu stack. Make this
even faster by putting the sysenter stack in the per-CPU TSS, so
that we can use the tss->esp0 value directly (which we have to
update on task switches anyway).
CAREFUL! This needs very subtle code for debug and NMI exceptions,
to make sure we don't run with the sysenter stack in any real kernel
code!

[PATCH] revert "noirqbalance still doesn't do anything"
This recent patch caused Nick Piggin's 2xPIII VIA686B chipset machine into an
interrupts-off lockup during IDE probing.
We don't really know why - it might be because an interrupt is delivered to a
secondary which doesn't expect it.
I have a second patch from Zwane which solves the same problem in a different
way, but until that's had some wider testing I suggest we just back off the
original.

<hch@lst.de>
[PATCH] remove devfs_only()
Rationale: devfs_only does nothing but disabling {un,}register_blkdev
and {un,}register_chrdev. {un,}register_blkdev already do nothing but
adding it's name argument to a lookup table for the __bdevname and
/proc/device output so this use is already bogus. The disabling of
the character device per-major arrays can work in practice but is
useless as any driver relying on it can't be used on non-devfs systems.

[PATCH] x86-64 updates for 2.5.64-bk3
Make x86-64 boot again after the INITIAL_JIFFIES changes
and some bug fixes. Also some work for NPTL.
- Merge with i386/2.5.64-bk3
- Fix memory leak in copy_thread
- arch_prctl uses GDT for base if possible. Cleanup.
- clone supports bases >32bit for SETTLS etc. %fs hardcoded now.
- new ptrace support for 64bit TLS
- Disable (set|get)_thread_* for 64bit processes.
- Audit arch/x86_64 for jiffies wrap issues.
- Fix initial jiffies problem (that caused hanging kernels)
- FIx a few 32bit emulation bugs (sigaltstack, sigqueue)
- Some cleanup from Pavel
- Should compile again as UP
- Shrink size a bit by not putting exception tables into object files.
- Fix compilation with gcc 3.3 :- force inlining when needed
- Work around 2.5.64-bk3 console init bug.

[PATCH] fix console ordering default
The conversion of the console registration to an initcall-style thing has
broken lots of people's setups. It is now dependent upon linkage order and
if you have both CONFIG_VT_CONSOLE and CONFIG_SERIAL_CONSOLE, no boot
messages come out on the screen because the kernel is selecting the serial
console first.
It can be fixed by specifying console=tty0, but nobody is doing that.
We can fix it up by placing drivers/char/ in front of drivers/serial/ in
linkage order.

[PATCH] Force cache alignment of task_structs
I enabled the advanced use-after-free detector for large slab objects and the
kernel oopsed. This is because that debug code adds things at the head of
the slab objects, and the kernel will die if task_structs are not
well-aligned.
The way to tell the slab allocator that it is not allowed to misalign objects
from this slab is SLAB_MUST_HWCACHE_ALIGN.

[PATCH] ext3: error handling robustness
Fix a couple of ext3 error handling routines to not assume that the
superblock has valid journal and buffer_head pointers. These functions are
called during mount and unmount and that may not be true.
This should fix the oops which Zwane saw when mounting a corrupt filesystem.
<akpm@digeo.com>
[PATCH] ext2: fix directory handling bug
Patch from Dave Miller. Fixes a very long-standing bug.
If a process has an fd open against a now-removed directory, lookups on that
fd will end up calling ext2_find_entry() against a zero-length directory.
When this happens ext2_find_entry() will, on the first pass through the loop,
set `kaddr' to page_address(page) - 20. Things get confused and the "zero
length directory entry" warning triggers.
This only happens on 64-bit machines, because ext2_last_byte() is returning
an unsigned (32-bit) value, and the arithmetic works out OK for 32-bit
machines.
So we change ext2_find_entry() to bale out immediately if the directory is
zero-length. All other directory-walking functions do this, but
ext2_find_entry() forgot to, due to the search-from-the-last-place
optimisation.

driver model: add bus_rescan_devices()
From Ben Collins
Used as manual trigger for device/driver binding, so drivers can claim
devices that are present but failed to be bound. In case of ieee1394, this
can happen if two computers are attached to a device - the second one won't
be able to claim it until the first detaches.
Changed device_attach() to return 1 when a driver was bound to a device.
Makes it so bus_rescan_devices() can return the number of devices attached.
Tested this with ieee1394 over a bus reset and it worked as expected.

[PATCH] Memleak in KOBIL USB Smart Card Terminal Driver
There is a memleak on error exit path in KOBIL USB Smart Card Terminal
Driver in both current 2.4 and 2.5.
See the patch.
Found with help of smatch + enhanced unfree script.

[PATCH] USB: Patch for DSBR-100 driver
I since you are listed as the maintainer of the USB subsystem and
I can't really see who else applies, I'm sending you a patch to my
driver for the DSBR-100 USB radio. This is mainly code cosmetics
(fixed ugly missing spaces after commas I inherited from the
aztech driver, some constants moved to preprocessor symbols), but
there's one technical change: I used to stop the radio when my
file descriptor was closed. Petr Slansky <slansky@usa.net>
pointed out that the other radio drivers don't do that, so
now I just let the radio run.

[PATCH] fix possible NULL pointer dereference in scsi_scan.c
If the sdev allocation fails and q is non-null we could dereference
sdev->request_queue. While at it reformat the function to use
goto-based cleanup - that's much easier to parse.

scsi_softirq queue is now list_head, eliminate bh_next
The following patch gets rid of softscsi_data struct and
array for the more manageable
static struct list_head done_q[NR_CPUS] __cacheline_aligned;
Thus, scsi_cmnd::bh_next is eliminated, since it was used only
in the scsi softirq processing code.
The comments are updated.
80 chars per line for the affected functions: scsi_done()
and scsi_softirq().
Eliminated is the double loop in scsi_softirq() -- this is
better handled in do_softirq() and gives the system a ``breather''.
(There are pros and cons for either side and if you guys
think that it was better with the double loop, I'll change it and
resubmit the patch.)

There are five functions that use jiffies. You fixed three of them.
If this change is done (and that's fine with me) it should be done
with this patch:

[PATCH] Re: hot scsi disk resize
Hi!
Here is new version of the patch. All procfs-related stuff has been removed.
One may rescan device size writing something to /sysfs/.../<scsi device>/rescan:
root@zefir:~# echo 1 >/sysfs/bus/scsi/devices/0\:0\:1\:0/rescan
root@zefir:~# dmesg
scsi0:A:1:0: Tagged Queuing enabled. Depth 64
scsi: host 0 channel 0 id 1 lun16384 has a LUN larger than allowed by the host adapter
SCSI device sda: 2097152 512-byte hdwr sectors (1074 MB)
SCSI device sda: drive cache: write through
sda: unknown partition table
Attached scsi disk sda at scsi0, channel 0, id 1, lun 0

[PATCH] aacraid driver for 2.5
This changes the cmd_per_lun element of the aacraid Scsi_Host_Template
to 1. The larger number is not needed and exceeds the depth limit for
scsi_adjust_queue_depth. Also updated struct initializers.

[PATCH] scsi_debug in 2.5.64
Here is a second attempt to patch scsi_debug in
2.5.64 . My reference version was out of sync in
my previous posting.
Changelog:
- add recovered error injection (this is a bit
different to the patch proposed by Kurt Garloff)
- fix flakiness in scsi_cmnd::result when errors
are being injected
- fix medium error injection
- make "every_nth" writeable in sysfs
- small re-arrangement of error flags in "opts"
- clean up some of the naming
Updated http://www.torque.net/sg/sdebug25.html
This patch does not include Mike Anderson's sysfs
probe() cleanup.
In 2.5.64 scsi error handling is flaky and sysfs is
especially flaky in 2.5.64-bk3. I'll send some finding
to the list when things stabilize a bit. [For anyone
who is bored, try following the tortured sequence
of scsi commands generated by the block/sd/mid-level
layers in response to a persistent medium error.]

[PATCH] reduce stack in qlogicfc.c
This is a start on reducing the stack usage in qlogicfc.c::
isp2x00_make_portdb(). I think that the stack reduction portion
of it is fine, but I'm concerned about the function returning
early due to kmalloc() failure, without making the port database.
[reduces stack from 0xc38 to 0x34 bytes (P4 UP, gcc 2.96)]
Can anyone suggest way(s) to have the isp2x00_make_portdb() function
called over and over again until it gets its job done?
Or does anyone even still use this driver?

[PATCH] sg version 3.5.28 for lk 2.5.64
Changelog:
- remove hosts, host_strs and host_hdr from sg's
procfs interface **
- add sysfs interface for allow_dio, def_reserved_size
and version ***
- switch boot time and module parameters to Rusty's
moduleparam.h interface. This means, for example,
the boot time "sg_def_reserved_size" parameter
changes to "sg.def_reserved_size".
** Christoph moved the host listing functionality into
a more central sysfs position (i.e. not dependent on
sg). However scsi_debug is the only LLD that I can
get to post any "host" info under the new arrangement.
Should devices, device_strs and device_hdrs also be
moved out of sg's procfs interface?
*** I find sg's "debug" in its procfs interface very
useful for debugging (sg itself amongst other things).
However it does not seem suitable for sysfs. Should
it move?

[PATCH] md: Missing mddev_put in md resync code
Whenever a ITERATE_MDDEV loop is exitted abnormally
we need to mddev_put the current mddev. There was
one point in md_do_sync where we didn't so use counts
became wrong.
<neilb@cse.unsw.edu.au>
[PATCH] md: Convert /proc/mdstat to use seq_file
From: Angus Sawyer <angus.sawyer@dsl.pipex.com>
Mainly straightforward convert of sprintf -> seq_printf. seq_start and
seq_next modelled on /proc/partitions. locking/ref counting as for
ITERATE_MDDEV.
pos == 0 -> header
pos == n -> nth mddev
pos == 0x10000 -> tail

[PATCH] md: Opencode flush_curr_signals in md.c
It is (now) too trivial to even have an inline.
<neilb@cse.unsw.edu.au>
[PATCH] md: Tidy up recovery_running flags in md
Md uses ->recovery_running and ->recovery_err to keep track of the
status or recovery. This is rather ad hoc and race prone.
This patch changes it to ->recovery which has bit flags for various
states.
