    Yeah, then, remove alloc_pages_any_node(). I can't really see the
    point of any_/exact_node. alloc_pages() and alloc_pages_node() are
    fine and in line with other functions. Why change it?

    The name is fine. Just clean up the users and make the intended usage
    clear in documentation and implementation (ie. trigger a big fat
    warning) and make all the callers use named constants instead of -1
    for special meanings.
