for more generic atomic").

Arun Sharma 60063497a9 atomic: use <linux/atomic.h>
This allows us to move duplicated code in <asm/atomic.h>
(atomic_inc_not_zero() for now) to <linux/atomic.h>

Andrew Morton 1fb8812ba5 [SPARC32]: Build fix.
Fix 6197fe4d72

arch/sparc/lib/atomic32.c: In function '__cmpxchg_u32':
arch/sparc/lib/atomic32.c:127: error: 'addr' undeclared (first use in this function)
arch/sparc/lib/atomic32.c:127: error: (Each undeclared identifier is reported only once
arch/sparc/lib/atomic32.c:127: error: for each function it appears in.)

I assume this is what was intended..

Robert Reif 74e61dee2a [SPARC32]: Fix SMP build regression
commit b19cbe2a16 [BRIDGE]: Fix fdb RCU
race

breaks sparc SMP build because atomic_add_unless is not exported.

This patch exports atomic_add_unless and atomic_cmpxchg.

David S. Miller 8a8b836b91 [SPARC]: Make bitops use same spinlocks as atomics.
Recent workqueue changes basically make this a formal requirement.

Also, move atomic32.o from lib-y to obj-y since it exports symbols
to modules.

Paul Jackson 1d66a79dc8 [SPARC]: atomic_clear_mask build fix
This fixes one build error introduced in sparc with the patch of Oct 30,
resent Nov 4 "[patch 3/5] atomic: atomic_inc_not_zero" I still can't get
sparc to build, but at least it gets further after I remove this line. 
Apparently, this change was agreed to by Andrew and Nick on Nov 14, but
everyone thought someone else was doing it.

Nick Piggin 8426e1f6af [PATCH] atomic: inc_not_zero
Introduce an atomic_inc_not_zero operation.  Make this a special case of
atomic_add_unless because lockless pagecache actually wants
atomic_inc_not_negativeone due to its offset refcount.

Ingo Molnar a9f6a0dd54 [PATCH] more SPIN_LOCK_UNLOCKED -> DEFINE_SPINLOCK conversions
This converts the final 20 DEFINE_SPINLOCK holdouts.  (another 580 places
are already using DEFINE_SPINLOCK).  Build tested on x86.

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!
