locking/rwsem, x86: Add frame annotation for call_rwsem_down_write_failed_killable() 3387a535ce62 ("x86/asm: Create stack frames in rwsem functions") has added FRAME_{BEGIN,END} annotations to rwsem asm stubs. The patch which has added call_rwsem_down_write_failed_killable() was based on an older tree so it didn't know about annotations. Let's add them. This addresses the following objtool warning: arch/x86/lib/rwsem.o: warning: objtool: call_rwsem_down_write_failed_killable()+0xe: call without frame pointer save/setup Reported-by: Ingo Molnar <mi...@kernel.org> Signed-off-by: Michal Hocko <mho...@suse.com> Cc: Andrew Morton <a...@linux-foundation.org> Cc: Linus Torvalds <torva...@linux-foundation.org> Cc: Peter Zijlstra <pet...@infradead.org> Cc: Thomas Gleixner <t...@linutronix.de> Cc: linux-a...@vger.kernel.org Cc: linux...@kvack.org Link: http://lkml.kernel.org/r/1460541432-21631-1-git-send-email-mho...@kernel.org Signed-off-by: Ingo Molnar <mi...@kernel.org> --- arch/x86/lib/rwsem.S | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/x86/lib/rwsem.S b/arch/x86/lib/rwsem.S index 4534a7e..a37462a 100644 --- a/arch/x86/lib/rwsem.S +++ b/arch/x86/lib/rwsem.S @@ -107,10 +107,12 @@ ENTRY(call_rwsem_down_write_failed) ENDPROC(call_rwsem_down_write_failed) ENTRY(call_rwsem_down_write_failed_killable) + FRAME_BEGIN save_common_regs movq %rax,%rdi call rwsem_down_write_failed_killable restore_common_regs + FRAME_END ret ENDPROC(call_rwsem_down_write_failed_killable)
