arm64 sys_membarrier number is already wired for arm64 through asm-generic/unistd.h, but needs to be allocated separately for the 32-bit compability layer of arm64. [ Untested on this architecture. 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@xxxxxxxxxxxx> CC: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> CC: linux-api@xxxxxxxxxxxxxxx CC: Catalin Marinas <catalin.marinas@xxxxxxx> CC: Will Deacon <will.deacon@xxxxxxx> --- arch/arm64/include/asm/unistd32.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm64/include/asm/unistd32.h b/arch/arm64/include/asm/unistd32.h index cef934a..d97be80 100644 --- a/arch/arm64/include/asm/unistd32.h +++ b/arch/arm64/include/asm/unistd32.h @@ -797,3 +797,5 @@ __SYSCALL(__NR_memfd_create, sys_memfd_create) __SYSCALL(__NR_bpf, sys_bpf) #define __NR_execveat 387 __SYSCALL(__NR_execveat, compat_sys_execveat) +#define __NR_membarrier 388 +__SYSCALL(__NR_membarrier, sys_membarrier) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
