    Looks sane to me. I've always wanted to encode the nid in the section.
    But, never had a compelling reason to do so.

    With this code in place, we could optimize the pfn_to_nid() routines to
    now obtain the nid from the section (rather than page struct). However,
    I'm not sure this is worth the effort.
