Great - I have pushed the commits out into the locking tree, they can be found
in:
git fetch git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git
locking/core
The PowerPC preparatory commit from you is:
0476a632cb3a: locking/atomics/powerpc: Move cmpxchg helpers to asm/cmpxchg.h
and define the full set of cmpxchg APIs
Thanks,
Ingo
