From d39886a7d31e0182f8b7e3b0e953e636b0af96fd Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Sun, 27 Dec 2015 15:04:42 +0200 Subject: tile: define __smp_xxx This defines __smp_xxx barriers for tile, for use by virtualization. Some smp_xxx barriers are removed as they are defined correctly by asm-generic/barriers.h Note: for 32 bit, keep smp_mb__after_atomic around since it's faster than the generic implementation.
