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