[SPARC32]: Build fix.

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..

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

[SPARC32]: Fix SMP build regression

2007-03-27T04:49:13+00:00

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.

[PATCH] sparc32 rwlock fix

2006-10-08T19:32:35+00:00

read_trylock() is broken on sparc32 (doesn't build and didn't work
right, actually).  Proposed fix:

 - make "writer holds lock" distinguishable from "reader tries to grab
   lock"

 - have __raw_read_trylock() try to acquire the mutex (in LSB of lock),
   terminating spin if we see that there's writer holding it.  Then do
   the rest as we do in read_lock().

Thanks to Ingo for discussion...

[SPARC]: Don't zero out tail during copy_from_user_inatomic().

2006-09-29T23:12:41+00:00

Actually, since we use the same code for all the copying
types in and out of userspace, we check at runtime whether
preemption is disabled.

[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.
