In arch/powerpc, arch/x86, and mm/page_alloc code to setup nr_node_ids based on
node_possible_map is duplicated.
This patchset switches those copies to calling the function provided by
page_alloc.

Linuxppc-dev mailing list
Linuxppc-dev@lists.ozlabs
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.
