    I prefer defining "__nodeinit" for __cpuinit and __meminit case to
    __devinit. __devinit is used many devices like I/O, and it is
    useful for many desktop users. But, cpu/memory hotpluggable box
    is very rare. And it should be in init section for many people.

    This kind of issue is caused by initialization of pgdat/zone.
    I think __nodeinit is enough and desirable.

    Bye.
