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
