    It all depends on what we mean by "per-cpu state". If we were to remember
    that "CPU 7 needs 0x1234 in register 44" then that would be wrong. But
    remembering some high-level functional thing like "CPU 7 needs to run the
    NMI watchdog" is fine. The CPU bringup code can work out whether that is
    possible, and how to do it.
