  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.

• 6b4977ce0   [PATCH] Use atomic64_set for 64-bit case of atomic_long_set ... Browse Code »

  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.

• d3cb48714   [PATCH] atomic_long_t & include/asm-generic/atomic.h V2 ... Browse Code »

  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.
