Peter Zijlstra 8715466b60 arch,arm64: Convert smp_mb__*() ... AARGH64 uses ll/sc primitives that do not imply any barriers for the normal atomics, therefore smp_mb__{before,after} should be a full barrier. Since AARGH64 doesn't use asm-generic/barrier.h, add the required definitions to its asm/barrier.h. Signed-off-by: Peter Zijlstra <peterz@infradead.org> Acked-by: Paul E.
