Uros Bizjak 8491d1bdf5 sched/clock: Use try_cmpxchg64 in sched_clock_{local,remote} 
Use try_cmpxchg64 instead of cmpxchg64 (*ptr, old, new) != old in
sched_clock_{local,remote}. x86 cmpxchg returns success in ZF flag,
so this change saves a compare after cmpxchg (and related move
instruction in front of cmpxchg).
