    Can't you just have the simple single and double loops in mmzone.h,
    seperated by a #ifdef CONFIG_DISCONTIGMEM?

    I like the general abstraction idea of where you're going though.
    Is there a for_each_node already? Can't see one:

    #define for_each_node(nid) \
    for (nid = 0; nid < numnodes; nid++)

    would allow us to change the assumption that nodes are numbered
    contiguously, starting from 0, more easily later on ... ?

    M.
