[PATCH] powerpc numa: Consolidate handling of Power4 special case
Code to handle Power4's invalid node id (0xffff) is duplicated for cpu and memory. Better to handle this case in one place -- of_node_to_nid. Overall behavior should be unchanged. Signed-off-by: Nathan Lynch <nathanl@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
