414edcd32a [PATCH] vt: fix possible memory corruption in complement_pos
Based on a patch from Andr Pereira de Almeida <andre@cachola.com.br>

It might be possible for the saved pointer (*p) to become invalid in
between vc_resizes, so saving the screen offset instead of the screen
pointer is saner.

This bug is very hard to trigger though, but Andre probably did, if he's
submitting this patch.  Anyway, with Andre's patch, it's still possible for
the offsets to be still illegal, if the new screen size is smaller than the
old one.  So I've also added checks if the offsets are still within the
screenbuffer size.

e752dd6cc6 [PATCH] fix send_sigqueue() vs thread exit race
posix_timer_event() first checks that the thread (SIGEV_THREAD_ID case)
does not have PF_EXITING flag, then it calls send_sigqueue() which locks
task list.  But if the thread exits in between the kernel will oops
(->sighand == NULL after __exit_sighand).

This patch moves the PF_EXITING check into the send_sigqueue(), it must be
done atomically under tasklist_lock.  When send_sigqueue() detects exiting
thread it returns -1.  In that case posix_timer_event will send the signal
to thread group.

Also, this patch fixes task_struct use-after-free in posix_timer_event.

a97c9bf33f [PATCH] fix cramfs making duplicate entries in inode cache
Every time cramfs_lookup() is called to lookup and inode for a dentry,
get_cramfs_inode() will allocate a new inode without checking to see if that
inode already exists in the inode cache.

This is fine the first time, but if the dentry cache entry(ies) associated
with that inode are aged out, but the inode entry is not aged out (which can
be quite common if the inode has buffer cache linked to it), cramfs_lookup()
will be called again and another inode will be allocated and added to the
inode cache creating a duplicate in the inode cache.

The big issue here is that the buffers associated with each inode cache entry
are not shared between the duplicates!

The older inode entries are now orphaned as no dentry points to it and won't
be freed until the buffer cache assoicated with them are first freed.  The
newest entry will have to create all new buffer cache for each part of its
file as the old buffer cache is now orphaned as well.

Patch below fixes this by making get_cramfs_inode() use the inode cache before
blindly creating a new entry every time.  This eliminates the duplicate inodes
and duplicate buffer cache.

0730ded5be [PATCH] remove a redundant variable in sys_prctl()
The patch removes a redundant variable `sig' from sys_prctl().

For some reason, when sys_prctl is called with option == PR_SET_PDEATHSIG
then the value of arg2 is assigned to an int variable named sig.  Then sig
is tested with valid_signal() and later used to set the value of
current->pdeath_signal .

There is no reason to use this intermediate variable since valid_signal()
takes a unsigned long argument, so it can handle being passed arg2
directly, and if the call to valid_signal is OK, then we know the value of
arg2 is in the range zero to _NSIG and thus it'll easily fit in a plain int
and thus there's no problem assigning it later to current->pdeath_signal
(which is an int).

The patch gets rid of the pointless variable `sig'.
This reduces the size of kernel/sys.o in 2.6.13-rc6-mm1 by 32 bytes on my
system.

Patch has been compile tested, boot tested, and just to make damn sure I
didn't break anything I wrote a quick test app that calls
prctl(PR_SET_PDEATHSIG ...) with the entire range of values for a
unsigned long, and it behaves as expected with and without the patch.

6c9c0b52b8 [PATCH] largefile support for accounting
There is a problem in the accounting subsystem in the kernel can not
correctly handle files larger than 2GB.  The output file containing the
process accounting data can grow very large if the system is large enough
and active enough.  If the 2GB limit is reached, then the system simply
stops storing process accounting data.

Another annoying problem is that once the system reaches this 2GB limit,
then every process which exits will receive a signal, SIGXFSZ.  This signal
is generated because an attempt was made to write beyond the limit for the
file descriptor.  This signal makes it look like every process has exited
due to a signal, when in fact, they have not.

The solution is to add the O_LARGEFILE flag to the list of flags used to
open the accounting file.  The rest of the accounting support is already
largefile safe.

The changes were tested by constructing a large file (just short of 2GB),
enabling accounting, and then running enough commands to cause the
accounting data generated to increase the size of the file to 2GB.  Without
the changes, the file grows to 2GB and the last command run in the test
script appears to exit due a signal when it has not.  With the changes,
things work as expected and quietly.

There are some user level changes required so that it can deal with
largefiles, but those are being handled separately.

do_unblank_screen at drivers/char/vt.c:2822 (Not tainted)

it, because hardirq.h isn't included in the oprofile code.  I hit this as a
bug when working with a patch which (indirectly) adds a #include of
hardirq.h to oprofile.

Regardless, the name collision is probably not a good idea, so this patch
fixes it, renaming the oprofile function to op_nmi_exit().  It also renames
the nmi_init() and nmi_timer_init() functions similarly, for consistency.

4b0dc07e66 [PATCH] cleanup of deadline_dispatch_requests()
cleanup of deadline_dispatch_requests():

- replace drq selection with hopefully clearer while semantically the
  same construct: take write request, if there is any, otherwise take read
  one, or NULL if none exist.

- kill unused other_dir.

ffdfc40976 [PATCH] Add rdinit parameter to pick early userspace init
Since early userspace was added, there's no way to override which init to
run from it.  Some people tack on an extra cpio archive with a link from
/init depending on what they want to run, but that's sometimes impractical.

Changing the "init=" to also override the early userspace isn't feasible,
since it is still used to indicate what init to run from disk when early
userspace has completed doing whatever it's doing (i.e.  load filesystem
modules and drivers).

Instead, introduce "rdinit=" and make it override the default "/init" if
specified.

2b579beec2 [PATCH] proc: link count fix
This patch fixes bug titled "sunrpc as module and bad proc/sys link count"
reported by Jiri Slaby.

The problem was, that only proc_dir_entry->nlink was updated and the
corresponding inode->i_nlink was not.  The fix is to implement the
inode->getattr() method, and update i_nlink (if necessary).

A quick audit of proc code shows that no other attribute changes after
creation.

230649da7c [PATCH] create_workqueue_thread() signedness fix
With "-W -Wno-unused -Wno-sign-compare" I get the following compile warning:

  CC      kernel/workqueue.o
kernel/workqueue.c: In function `workqueue_cpu_callback':
kernel/workqueue.c:504: warning: ordered comparison of pointer with integer zero

On error create_workqueue_thread() returns NULL, not negative pointer, so
following trivial patch suggests itself.

f3ef6f63e5 [PATCH] Speedup FAT filesystem directory reads
OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>

This speeds up directory reads for large FAT partitions, if the buffercache
has to be filled from the drive. Following values were taken from:

        $ time find path_to_freshly_mounted_fat > /dev/null

on an otherwise idle system.

FAT with 16KB Clusters on IDE attached drive:   Factor  2
FAT with 32KB Clusters on USB2 attached drive:  Factor 10 (!)
Its less than 1/10 slower, if the buffercache is uptodate.

The patch introduces the new function fat_dir_readahead().

fat_dir_readahead() calls sb_breadahead() to readahead a whole cluster,
if the requested sector is the first one in a cluster.
It is usefull to do this, because on FAT directories occupy whole
clusters, with the exception of FAT12/FAT16 root dirs.

Readahead is only done, if the cluster's first sector is not uptodate
to avoid overhead, when the buffer cache is already uptodate.
Note that under memory pressure, the maximal byte count wasted
(read: has to be red from disk twice) is 1 cluster's size.  Thats 64KB.

fat_dir_readahead() is called from fat__get_entry().

There is also an unrelated cleanup at one spot:

        if (bh)
                brelse(bh);

is replaced with:

        brelse(bh);

brelse() can handle NULL pointer arguments by itself.

378bac820b [PATCH] flush icache early when loading module
Change the sequence of operations performed during module loading to flush
the instruction cache before module parameters are processed.  If a module
has parameters of an unusual type that cannot be handled using the standard
accessor functions param_set_xxx and param_get_xxx, it has to to provide a
set of accessor functions for this type.  This requires module code to be
executed during parameter processing, which is of course only possible
after the icache has been flushed.
