 A set of locking related fixes and updates:
 
   - Two fixes for the futex syscall related to the timeout handling.
 
     FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and because
     it's not set the time namespace adjustment for clock MONOTONIC is
     applied wrongly.
 
     FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
     always a relative timeout.
 
   - Cleanups in the futex syscall entry points which became obvious when
     the two timeout handling bugs were fixed.
 
   - Cleanup of queued_write_lock_slowpath() as suggested by Linus
 
   - Fixup of the smp_call_function_single_async() prototype
