2007-05-08	atomic.h: atomic_add_unless as inline. Remove system.h atomic.h circular dependency	Mathieu Desnoyers	1	-5/+12
	atomic_add_unless as inline. Remove system.h atomic.h circular dependency. I agree (with Andi Kleen) this typeof is not needed and more error prone. All the original atomic.h code that uses cmpxchg (which includes the atomic_add_unless) uses defines instead of inline functions, probably to circumvent a circular dependency between system.h and atomic.h on powerpc (which my patch addresses). Therefore, it makes sense to use inline functions that will provide type checking. atomic_add_unless as inline. Remove system.h atomic.h circular dependency. Digging into the FRV architecture shows me that it is also affected by such a circular dependency. Here is the diff applying this against the rest of my atomic.h patches. It applies over the atomic.h standardization patches.

2006-01-15	[PATCH] Use atomic64_set for 64-bit case of atomic_long_set	Kyle McMartin	1	-1/+1
	For some reason, the BITS_PER_LONG == 64 case of atomic_long_set was using atomic_set instead of atomic64_set. This does not jive with architectures which use an inline instead of a #define to implement their atomic_set() primitives.

2006-01-06	[PATCH] atomic_long_t & include/asm-generic/atomic.h V2	Christoph Lameter	1	-0/+116
	Several counters already have the need to use 64 atomic variables on 64 bit platforms (see mm_counter_t in sched.h). We have to do ugly ifdefs to fall back to 32 bit atomic on 32 bit platforms. The VM statistics patch that I am working on will also make more extensive use of atomic64. This patch introduces a new type atomic_long_t by providing definitions in asm-generic/atomic.h that works similar to the c "long" type. Its 32 bits on 32 bit platforms and 64 bits on 64 bit platforms. Also cleans up the determination of the mm_counter_t in sched.h.
