    I think this approach is good to get the microcode applied as
    early as possible at boot time. But on servers you usually do not want
    to reboot the machine unless you do a BIOS update which will apply
    the new microcode anyway. So for applying the microcode update
    at runtime I would like to keep the existing API.
