Nicholas Piggin 0bfdf59890 powerpc/64: Fix smp_wmb barrier definition use use lwsync consistently ... asm/barrier.h is not always included after asm/synch.h, which meant it was missing __SUBARCH_HAS_LWSYNC, so in some files smp_wmb() would be eieio when it should be lwsync. kernel/time/hrtimer.c is one case. __SUBARCH_HAS_LWSYNC is only used in one place, so just fold it in to where it's used. Previously with my small simulator config, 377 instances of eieio in the tree. After this patch there are 55.
