I'm rebasing and resending this series because the hard
lockup messages are being seen in the field.

Since last time, one of the patches was merged, and patches
were split and reordered a bit. No major changes.

This still hasn't been tested with the FSP firmware update.

Thanks,
Nick

  powerpc: hard disable irqs in smp_send_stop loop
  powerpc/powernv: Always stop secondaries before reboot/shutdown

I have tested this series on a FSP platform with firmware update
and multiple reboot/shutdown tests. Not seen any issues.
