Krzysztof Benedyczak 5917583978 [PATCH] Make POSIX message queue sys_mq_open() honor umask
We ignored umask when creating new queues via mq_open (when creating
with open() on mqueue fs it is ok of course).  According to the
specification this a bug.  This trivial patch fixes this.

Mike Waychison 19b4946ca9 [PATCH] ipc: convert /proc/sysvipc/* to generic seq_file interface
Change the /proc/sysvipc/shm|sem|msg files to use the generic seq_file
implementation for struct ipc_ids.

Mike Waychison ae7817745e [PATCH] ipc: add generic struct ipc_ids seq_file iteration
The following two patches convert /proc/sysvipc/* to use seq_file.

This gives us the following:

 - Self-consistent IPC records in proc.
 - O(n) reading of the files themselves.

This patch:

Add a generic method for ipc types to be displayed using seq_file.  This
patch abstracts out seq_file iterating over struct ipc_ids into ipc/util.c

Stephen Rothwell 202e5979af [PATCH] compat: be more consistent about [ug]id_t
When I first wrote the compat layer patches, I was somewhat cavalier about
the definition of compat_uid_t and compat_gid_t (or maybe I just
misunderstood :-)).  This patch makes the compat types much more consistent
with the types we are being compatible with and hopefully will fix a few
bugs along the way.

	compat type		type in compat arch
	__compat_[ug]id_t	__kernel_[ug]id_t
	__compat_[ug]id32_t	__kernel_[ug]id32_t
	compat_[ug]id_t		[ug]id_t

The difference is that compat_uid_t is always 32 bits (for the archs we
care about) but __compat_uid_t may be 16 bits on some.

Ingo Molnar 00a5dfdb93 [PATCH] Fix semundo lock leakage
semundo->lock can leak if semundo->refcount goes from 2 to 1 while
another thread has it locked.  This causes major problems for PREEMPT
kernels.

The simplest fix for now is to undo the single-thread optimization.

This bug was found via relentless testing by Dominik Karall.

Andrew Morton 6ade43fbbc [PATCH] shm: CONFIG_SHMEM=n build fix
Fix bug found by Grant Coady <lkml@dodo.com.au>'s autobuild setup.

shmem_set_policy() and shmem_get_policy() are macros if !CONFIG_SHMEM, so this
doesn't work.

This patch fixes some minor bugs introduced by the previous patch (remove
old syscalls).  Both patches remove the obsolete syscalls.  The changes in
this patch were suggested by Arnd Bergmann.  The vmlinux.lds.S changes are
required for the latest gcc/binutils.

Jesse Millan 214a627cb4 [PATCH] put_compat_shminfo() warning fix
GCC 4 complains because the function put_compat_shminfo() can't get to its
return statement if there is no error...  If the function does not return
-EFAULT, it doesn't return anything at all.  Looks like a typo.

Manfred Spraul b78755abcd [PATCH] ipcsem: remove superflous decrease variable from sys_semtimedop
Patrick noticed that the initial scan of the semaphore operations logs
decrease and increase operations seperately, but then both cases are or'ed
together and decrease is never used.  The attached patch removes the
decrease parameter - it shrinks sys_semtimedop() by 56 bytes.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
