Message-ID: <20200706043540.1563616-1-npiggin@gmail.com> (raw)
v3 is updated to use __pv_queued_spin_unlock, noticed by Waiman (thank you).
Thanks,
Nick
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
