Uros Bizjak fea0e1820b locking/pvqspinlock: Use try_cmpxchg() in qspinlock_paravirt.h ... Use try_cmpxchg(*ptr, &old, new) instead of cmpxchg(*ptr, old, new) == old in qspinlock_paravirt.h x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg. No functional change intended.
