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@efficios.com> CC: Andrew Morton <akpm@linux-foundation.org> CC: linux-api@vger.kernel.org CC: Russell King <linux@arm.linux.org.uk> --- 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(-) diff --git a/arch/arm/include/asm/unistd.h b/arch/arm/include/asm/unistd.h index 32640c4..d93876c 100644 --- a/arch/arm/include/asm/unistd.h +++ b/arch/arm/include/asm/unistd.h @@ -19,7 +19,7 @@ * This may need to be greater than __NR_last_syscall+1 in order to * account for the padding in the syscall table */ -#define __NR_syscalls (388) +#define __NR_syscalls (389) /* * *NOTE*: This is a ghost syscall private to the kernel.
