[PATCH] atomic-powerpc-remove-double-defines

[Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>]

Remove duplicated defines in asm-powerpc/atomic.h. atomic64_inc_not_zero
and atomic64_xchg are defined twice. It also removes an unnecessary cast
to the atomic_cmpxchg result, which is already done by system.h cmpxchg.

It applies on 2.6.21-rc6-mm1.
