[ 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@efficios.com> CC: Andrew Morton <akpm@linux-foundation.org> CC: linux-api@vger.kernel.org CC: Ralf Baechle <ralf@linux-mips.org> CC: linux-mips@linux-mips.org --- arch/mips/include/uapi/asm/unistd.h | 15 +++++++++------ arch/mips/kernel/scall32-o32.S | 1 + arch/mips/kernel/scall64-64.S | 1 + arch/mips/kernel/scall64-n32.S | 1 + arch/mips/kernel/scall64-o32.S | 1 + 5 files changed, 13 insertions(+), 6 deletions(-) diff --git a/arch/mips/include/uapi/asm/unistd.h b/arch/mips/include/uapi/asm/unistd.h index d0bdfaa..b107983 100644 --- a/arch/mips/include/uapi/asm/unistd.h +++ b/arch/mips/include/uapi/asm/unistd.h @@ -378,16 +378,17 @@ #define __NR_bpf (__NR_Linux + 355) #define __NR_execveat (__NR_Linux + 356) #define __NR_mlock2 (__NR_Linux + 357) +#define __NR_membarrier (__NR_Linux + 358) /* * Offset of the last Linux o32 flavoured syscall */ -#define __NR_Linux_syscalls 357 +#define __NR_Linux_syscalls 358 #endif /* _MIPS_SIM == _MIPS_SIM_ABI32 */ #define __NR_O32_Linux 4000 -#define __NR_O32_Linux_syscalls 357 +#define __NR_O32_Linux_syscalls 358 #if _MIPS_SIM == _MIPS_SIM_ABI64 @@ -713,16 +714,17 @@ #define __NR_bpf (__NR_Linux + 315) #define __NR_execveat (__NR_Linux + 316) #define __NR_mlock2 (__NR_Linux + 317) +#define __NR_membarrier (__NR_Linux + 318) /* * Offset of the last Linux 64-bit flavoured syscall */ -#define __NR_Linux_syscalls 317 +#define __NR_Linux_syscalls 318 #endif /* _MIPS_SIM == _MIPS_SIM_ABI64 */ #define __NR_64_Linux 5000 -#define __NR_64_Linux_syscalls 317 +#define __NR_64_Linux_syscalls 318 #if _MIPS_SIM == _MIPS_SIM_NABI32 @@ -1052,15 +1054,16 @@ #define __NR_bpf (__NR_Linux + 319) #define __NR_execveat (__NR_Linux + 320) #define __NR_mlock2 (__NR_Linux + 321) +#define __NR_membarrier (__NR_Linux + 322) /* * Offset of the last N32 flavoured syscall */ -#define __NR_Linux_syscalls 321 +#define __NR_Linux_syscalls 322 #endif /* _MIPS_SIM == _MIPS_SIM_NABI32 */ #define __NR_N32_Linux 6000 -#define __NR_N32_Linux_syscalls 321 +#define __NR_N32_Linux_syscalls 322 #endif /* _UAPI_ASM_UNISTD_H */ diff --git a/arch/mips/kernel/scall32-o32.S b/arch/mips/kernel/scall32-o32.S index b0b377a..9265542 100644 --- a/arch/mips/kernel/scall32-o32.S +++ b/arch/mips/kernel/scall32-o32.S @@ -600,3 +600,4 @@ EXPORT(sys_call_table) PTR sys_bpf /* 4355 */ PTR sys_execveat PTR sys_mlock2 + PTR sys_membarrier diff --git a/arch/mips/kernel/scall64-64.S b/arch/mips/kernel/scall64-64.S index f12eb03..79d4fb0 100644 --- a/arch/mips/kernel/scall64-64.S +++ b/arch/mips/kernel/scall64-64.S @@ -437,4 +437,5 @@ EXPORT(sys_call_table) PTR sys_bpf /* 5315 */ PTR sys_execveat PTR sys_mlock2 + PTR sys_membarrier .size sys_call_table,.-sys_call_table diff --git a/arch/mips/kernel/scall64-n32.S b/arch/mips/kernel/scall64-n32.S index ecdd65a..235892a 100644 --- a/arch/mips/kernel/scall64-n32.S +++ b/arch/mips/kernel/scall64-n32.S @@ -430,4 +430,5 @@ EXPORT(sysn32_call_table) PTR sys_bpf PTR compat_sys_execveat /* 6320 */ PTR sys_mlock2 + PTR sys_membarrier .size sysn32_call_table,.-sysn32_call_table diff --git a/arch/mips/kernel/scall64-o32.S b/arch/mips/kernel/scall64-o32.S index 7a8b2df..c051bd3 100644 --- a/arch/mips/kernel/scall64-o32.S +++ b/arch/mips/kernel/scall64-o32.S @@ -585,4 +585,5 @@ EXPORT(sys32_call_table) PTR sys_bpf /* 4355 */ PTR compat_sys_execveat PTR sys_mlock2 + PTR sys_membarrier .size sys32_call_table,.-sys32_call_table -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
