Nicholas Piggin (6):
  powerpc/powernv: must include hvcall.h to get PAPR defines
  powerpc/pseries: move some PAPR paravirt functions to their own file
  powerpc: move spinlock implementation to simple_spinlock
  powerpc/64s: implement queued spinlocks and rwlocks
  powerpc/pseries: implement paravirt qspinlocks for SPLPAR
  powerpc/qspinlock: optimised atomic_try_cmpxchg_lock that adds the
    lock hint
