[PATCH] wait_table and zonelist initializing for memory hotadd: wait_table initialization

Wait_table is initialized according to zone size at boot time.  But, we cannot
know the maixmum zone size when memory hotplug is enabled.  It can be
changed....  And resizing of wait_table is hard.

So kernel allocate and initialzie wait_table as its maximum size.
