Subject: [v2 PATCH 0/3] Use NMI to stop cpus

This patch series attempts to use NMI to stop cpus instead of the
REBOOT_VECTOR irq.  The idea is to have a more robust and reliable
way to stop cpus when serializing things like the panic path.

More details in the changelogs.

Don Zickus (3):
  x86, reboot:  Use NMI instead of REBOOT_VECTOR to stop cpus
  x86, NMI: Add NMI IPI selftest
  x86, NMI: knob to disable using NMI IPIs to stop cpus
