[Nicholas Piggin]

Hi,

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

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
