From: Michal Hocko <mhocko@xxxxxxxx>
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.
