Subject: [PATCH v2 0/6] powerpc: queued spinlocks and rwlocks
Date: Fri, 3 Jul 2020 17:35:10 +1000 [thread overview]
Message-ID: <20200703073516.1354108-1-npiggin@gmail.com> (raw)
v2 is updated to account for feedback from Will, Peter, and
Waiman (thank you), and trims off a couple of RFC and unrelated
patches.
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
