linux-toradex.git/arch/powerpc/include/asm/mutex.h, branch v3.4.18 Linux kernel for Apalis and Colibri modules powerpc: Rename LWSYNC_ON_SMP to PPC_RELEASE_BARRIER, ISYNC_ON_SMP to PPC_ACQUIRE_BARRIER 2010-02-17T03:03:15+00:00 Anton Blanchard anton@samba.org 2010-02-10T01:04:06+00:00 f10e2e5b4b4c9937de596f96ffe028be3a565598 For performance reasons we are about to change ISYNC_ON_SMP to sometimes be lwsync. Now that the macro name doesn't make sense, change it and LWSYNC_ON_SMP to better explain what the barriers are doing.

powerpc: Optimise mutex 2008-11-19T05:04:58+00:00 Nick Piggin npiggin@suse.de 2008-11-11T17:54:15+00:00 ae564c63b8311fa73c21e456e00dba1f4b1ff6bc This implements an optimised mutex fastpath for powerpc, making use of acquire and release barrier semantics. This takes the mutex lock+unlock benchmark from 203 to 173 cycles on a G5. Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Paul Mackerras <paulus@samba.org>

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.
