Add device info to the various reiserfs warnings and panics so you can tell

properly init device inodes in the acl code

From: Bart Samwel <bart@samwel.tk>

This patch from Micha Feigin fixes some bugs in the earlier reiserfs 
commit default patch. The changelog:

* If you remounted without any commit=NNN option, it would assume commit=0
  and restore the defaults.  This patch makes it leave the current state alone
  if you don't pass commit=NNN.

* Added range check for cast from unsigned long to unsigned int.

Fix the 3c905C 10/100 transceiver initialisation woes.

Currently, shrink_slab() will decide that it needs to scan a certain number of
dentries, will call shrink_dcache_memory() requesting that this be done, and
shrink_dcache_memory() will simply bale out without doing anything because the
caller did not have __GFP_FS.

This has the potential to disrupt our lovely pagecache-vs-slab balancing act. 
So change things so that shrinker callouts can return -1, indicating that they
baled out.  This way, shrink_slab can remember that this slab was owed a
certain number of scannings and these will be correctly performed next time a
__GFP_FS caller comes by.

From: Andi Kleen <ak@suse.de>

We still need some kind of early CPU detection, e.g.  for the AMD768
workaround and for the slab allocator to size its slabs correctly for the
cache line.  Also some other code already had private early CPU routines.

This patch takes a new approach compared to the previous patch which caused
Andrew so much grief.  It only fills in a few selected fields in
boot_cpu_data (only the data needed to identify the CPU type and the cache
alignment).  In particular the feature masks are not filled in, and the
other fields are also not touched to prevent unwanted side effects.

Also convert the ppro workaround to use standard cpu data now. 

I'm not sure if slab still has the necessary support to use the cache line
size early; previously Manfred showed some serious memory saving with this
for kernels that are compiled for a bigger cache line size than the CPU (is
often the case on distribution kernels).  This code could be reenable now
with this patch.

The patch fixes a problem with ES7000 Server Management mechanism that uses
platform register mip_port.  It was not initialized, so the mechanism was not
functional.

The patch also fixes the APIC destination for hierarchical and flat cluster
models used in ES7000.  The destination ID's reflect policies for Cascade
based systems which use logical delivery and lowest priority mechanism, and
for xAPIC based models that use physical delivery and fixed APIC destinations.

The patch also turns on NO_IOAPIC_CHECK (1) to avoid error messages and
attempts to re-write the ID, because on ES7000 all ID's are hard coded in the
BIOS and cannot be altered.

sys32_nfsservctl is the largest remaining syscall emulation handler that can
be consolidated.  mips and ia64 currently don't use this at all, parisc has a
simpler implementation than the one used by s390, sparc ppc and that the new
compat_sys_nfsservctl is based on.

The user access checks in the code are inconsistant at least, which should be
fixed here.

Compile tested only due to lack of proper test setup.

sys32_select has seven mostly but not exactly identical versions, so
consolidate them as compat_sys_select.  Based on the ppc64 implementation,
which most closely resembles sys_select.  One bug that was not caught by LTP
has been fixed since the first version of this patch.

From: Arnd Bergmann <arnd@arndb.de>

The code for sys32_execve/do_execve32 in most of the seven versions was copied
from fs/exec.c but not kept up-to-date.  The new compat_do_execve() function
is based on the mips code and has been resync'ed with do_execve().  IA64
changes are from Arun Sharma.

Tested on x86_64, ia64 and s390

From: Arnd Bergmann <arnd@arndb.de>

The seven implementations of this have gone out of sync and are mostly buggy. 
The new compat_sys_* version is based on the ppc64 implementation, which most
closely resembles the code in sys_readv/sys_writev.

Without disturbing the read/write ratio, increase the bathc expiry

Richard Atterer reported that mutt does not play well with noatime (it uses
access times to check whether new mail has arrived in a folder).  This patch
warns about this in the doc, and adds a setting to the control script to
disable the noatime remount.

This patch changes the SELinux module to try to reset any descriptors it
closes on exec (due to a lack of permission by the new domain to the inherited
open file) to refer to the null device.  This counters the problem of SELinux
inducing program misbehavior, particularly due to having descriptors 0-2
closed when the new domain is not allowed access to the caller's tty.  This is
primarily to address the case where the caller is trusted with respect to the
new domain, as the untrusted caller case is already handled via AT_SECURE and
glibc secure mode.  The code is partly based on the OpenWall LSM, which in
turn drew from the OpenWall kernel patch.  Note that the code does not
guarantee that the descriptor is always re-opened to /dev/null; it merely
makes a reasonable effort to do so, but can fail under various conditions.

From: Andreas Dilger <adilger@clusterfs.com>

a) we don't call ext3_error() for an IO error in ext3_find_entry(), so we
   won't do the normal ext3 error handling (mark SB in error, remount-ro
   or panic if desired);
b) in empty_dir() we don't continue checking for non-empty blocks after a
   content error (ext3_check_dir_entry() calls ext3_error() already);
c) we had decided not to mark the SB in error for holes in directories to
   allow leway in the indexed-directory implementation, but this change
   incorrectly also disabled marking the SB in error for real IO errors.

1) Create an in_sched_functions() function in sched.c and make the
   archs use it.  (Two archs have wchan #if 0'd out: left them alone).

2) Move __sched from linux/init.h to linux/sched.h and add comment.

3) Rename __scheduling_functions_start_here/end_here to __sched_text_start/end.

With strange workloads which do a lot of quick truncation on small filesystems
it is possible to get into a situation where there are free blocks on the
disk, but they are not allocatable at this time due to their having been freed
up in the current JBD transaction.  Applications get unexpected ENOSPC errors.

We can fix that with this patch, originally by Andreas Dilger which forces a
single commit+retry when an ENOSPC is encountered.

The real problem is that SMP with nmi_watchdog=2 initialises the lapic NMI
watchdog but doesn't check it and therefore doesn't reduce nmi_hz.  This is
an SMP bug.

The patch changes smpboot.c to do a check_nmi_watchdog() at the appropriate
place, which fixes the high NMI frequency problem w/o changing anything
else.  I've verified that it solves the problem on my MP-capable UP box.

From: Philippe Elie <phil.el@wanadoo.fr>

With nmi_watchdog=2 and a P4 ht box the nmi is occurring only on logical
processor 0, it's better to get it on both.

With this patch, on x86 SMP and nmi_watchdog=2, nmi interupts occur at 1000
hz (if the cpu is loaded) not at the intended 1 hz rate but that's a distinct
problem.

I am submitting a patch that fixes 2 race conditions in the 32 bit ioctl
emulation code.(fs/compat.c) Since the search is not locked; when a
ioctl_trans structure is deleted, corruption can occur.

The following scenarios discuss the race conditions:

1) When the search is hapenning, if any ioctl_trans structure gets
   deleted; then rather than searching the hash table, the code will start
   searching the free list.
