This allows us to move duplicated code in

2007-05-31T08:52:51+00:00

Fix 6197fe4d720ea3e2ee94cdc7ef32d6c0151199de

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..

[SPARC32]: Fix SMP build regression

commit b19cbe2a1695c09c74f83646c4b82b51123b3690 [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.

[SPARC]: Make bitops use same spinlocks as atomics.

2006-12-18T00:18:47+00:00

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.

[SPARC]: atomic_clear_mask build fix

2005-12-12T22:42:31+00:00

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.

[PATCH] atomic: inc_not_zero

2005-11-14T02:14:16+00:00

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.
