From: Michael S. Tsirkin Date: Mon, 21 Dec 2015 07:22:18 +0000 (+0200) Subject: arm64: reuse asm-generic/barrier.h X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=90ff6a17d0e07d689886cba4244674bfd41e7a2d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git arm64: reuse asm-generic/barrier.h On arm64 nop, read_barrier_depends, smp_read_barrier_depends smp_store_mb(), smp_mb__before_atomic and smp_mb__after_atomic match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to refactoring this code area. Signed-off-by: Michael S.
