    Subject[PATCH: 011/012] Memory hotplug for new nodes v.2 (Register start func for acpi_memhotplug)

    This is a patch to create start function which calls add_memory().
    Container driver can call add_memory() by this. If this is not,
    even if the node which is defined container device in DSDT is added,
    the container driver can't call memory hotplug code.
