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
