Subject: [PATCH v2 0/3] avoid secondary hold spinloop when possible
Date: Mon, 23 Oct 2017 18:05:04 +1000	[thread overview]
Message-ID: <20171023080507.21974-1-npiggin@gmail.com> (raw)

I've made this series only avoid the secondary spinloop on powernv.
pSeries is a little bit more complicated, some cases in kexec the
secondaries will be at 0x60. I haven't had time to get all that
sorted out for this merge window, so OPAL-only this time.

Nicholas Piggin (3):
  powerpc/powernv: Always stop secondaries before reboot/shutdown
  powerpc: use NMI IPI for smp_send_stop
  powerpc/powernv: Avoid waiting for secondary hold spinloop with OPAL
