[PATCH] pgdat allocation for new node add (get node id by acpi)
This is to find node id from acpi's handle of memory_device in DSDT. _PXM for the new node can be found by acpi_get_pxm() by using new memory's handle. So, node id can be found by pxm_to_nid_map[]. This patch becomes simpler than v2 of node hot-add patch. Because old add_memory() function doesn't have node id parameter. So, kernel must find its handle by physical address via DSDT again. But, v3 just give node id to add_memory() now.
