Steven Rostedt 52393ccc0a [PATCH] remove set_wmb - arch removal
set_wmb should not be used in the kernel because it just confuses the
code more and has no benefit.  Since it is not currently used in the
kernel this patch removes it so that new code does not include it.

All archs define set_wmb(var, value) to do { var = value; wmb(); }
while(0) except ia64 and sparc which use a mb() instead.  But this is
still moot since it is not used anyway.

Hasn't been tested on any archs but x86 and x86_64 (and only compiled
tested)

Ingo Molnar 36c8b58689 [PATCH] sched: cleanup, remove task_t, convert to struct task_struct
cleanup: remove task_t and convert all the uses to struct task_struct. I
introduced it for the scheduler anno and it was a mistake.

Conversion was mostly scripted, the result was reviewed and all
secondary whitespace and style impact (if any) was fixed up by hand.

Hirokazu Takata b04ec261bd [PATCH] m32r: __cmpxchg_u32 fix
This patch fixes a bug of include/asm-m32r/system.h:__cmpxchg_u32().

  static __inline__ unsigned long
  __cmpxchg_u32(volatile unsigned int *p, unsigned int old, unsigned int new);

In __cmpxchg_u32(), the "old" value must not be changed to the previous "*p"
value.  But the former code modifies the previous "*p" value.

A deadlock at _atomic_dec_and_lock sometimes happened due to this bug.

Hirokazu Takata 9287d95ea1 [PATCH] m32r: Support M32104UT target platform
This patch is for supporting a new target platform, Renesas M32104UT
evaluation board.

The M32104UT is an eval board based on an uT-Engine specification.  This board
has an MMU-less M32R family processor, M32104.
http://www-wa0.personal-media.co.jp/pmc/archive/te/te_m32104_e.pdf

This board is one of the most popular M32R platform, so we have ported
Linux/M32R to it.

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!
