    Paul, I just realized that this won't work. We actually need the default
    version of arch_init_sched_domains() which builds the default domain. It's
    used during bootup. It's only the hotplug event handling where we do not want
    the default.
    I could still redo the switch() statement as you suggested but it seems that
    it's not going to improve the readability that much at this point.
