To try it out: fetch linux-next/akpm, apply this patch, build/run a membarrier-enabled kernel, and do make kselftest. ] Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers-vg+e7yoeK/dWk0Htik3J/w@public.gmane.org> CC: Andrew Morton <akpm-de/tnXTf+JLsfHDXvbKv3WD2FQJk+8+b@public.gmane.org> CC: linux-api-u79uwXL29TY76Z2rM5mHXA@public.gmane.org CC: Russell King <linux-lFZ/pmaqli7XmaaqVzeoHQ@public.gmane.org> --- arch/arm/include/asm/unistd.h | 2 +- arch/arm/include/uapi/asm/unistd.h | 1 + arch/arm/kernel/calls.S | 1 + 3 files changed, 3 insertions(+), 1 deletion(-)
