    I'm using suspend-to-mem and it looks like its unplugging/replugging all
    the CPUs.

    The part of the question I don't quite understand is why this is
    considered per-CPU state? Surely NMI-watchdog is a system-wide thing?
    Or does this also tie into other uses of the performance registers which
    may be set per-CPU?
