Nick Piggin	957ab07b44	powerpc: Optimise smp_rmb ... After commit 598056d5af ("[POWERPC] Fix rmb to order cacheable vs. noncacheable"), rmb() becomes a sync instruction, which is needed to order cacheable vs noncacheable loads. However smp_rmb() is #defined to rmb(), and smp_rmb() can be an lwsync. This restores smp_rmb() performance by using lwsync there and updates the comments.

Nick Piggin	46d075be58	powerpc: Optimise smp_wmb ... Change 2d1b202762 ("powerpc: Fixup lwsync at runtime") removed __SUBARCH_HAS_LWSYNC, causing smp_wmb to revert back to eieio for all CPUs. This restores the behaviour intorduced in 74f0609526 ("powerpc: Optimise smp_wmb on 64-bit processors").

Stephen Rothwell	b8b572e101	powerpc: Move include files to arch/powerpc/include/asm ... from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc.
