Subject: [PATCH] memory hotplug: fix unnecessary calling of
 init_currenty_empty_zone()

zone->present_pages is updated in online_pages().  But, __add_zone() can be
called twice or more before calling online_pages().  So,
init_currenty_empty_zone() can be called unnecessary times.  It is cause of
memory leak of zone's wait_table.
