Subject: [PATCH 0/5] More NMI IPI enablement work
Date: Mon, 18 Sep 2017 18:27:01 +1000	[thread overview]
Message-ID: <20170918082706.6485-1-npiggin@gmail.com> (raw)

Hi,

Here is the NMI IPI enablement for powernv, which requires
supported firmware and hardware:

https://lists.ozlabs.org/pipermail/skiboot/2017-September/009111.html

And some preceeding patches that fix issues I ran into when
testing it.

Thanks,
Nick

  powerpc/watchdog: do not panic from locked CPU's IPI handler
  powerpc/watchdog: do not backtrace locked CPUs twice if allcpus
    backtrace is enabled
  powerpc/watchdog: do not trigger SMP crash from touch_nmi_watchdog
  powerpc/xmon: avoid tripping SMP hardlockup watchdog
  powerpc/powernv: implement NMI IPI with OPAL_SIGNAL_SYSTEM_RESET
