page_alloc: make setup_nr_node_ids() usable for arch init code
powerpc and x86 were opencoding copies of setup_nr_node_ids(), which page_alloc provides but makes static. Make it avaliable to the archs in linux/mm.h. Signed-off-by: Cody P Schafer <cody@linux.vnet.ibm.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
