Michael Ellerman 1f1676bb2d powerpc/barrier: Use CONFIG_PPC64 for barrier selection ... Currently we use ifdef __powerpc64__ in barrier.h to decide if we should use lwsync or eieio for SMPWMB which is then used by __smp_wmb(). That means when we are building the compat VDSO we will use eieio, because it's 32-bit code, even though we're building a 64-bit kernel for a 64-bit CPU. Although eieio should work, it would be cleaner if we always used the same barrier, even for the 32-bit VDSO. So change the ifdef to CONFIG_PPC64, so that the selection is made based on the bitness of the kernel we're building for, not the current compilation unit.
