    I can personally (and quite quickly) port the page size reductions to
    other VM's, as the changes required are not particularly invasive.

    I can correct style issues and the like for at least the bits I'm
    responsible for in very short order. I'll consolidate the waitqueue,
    ->virtual and ->zone removals within the hour, since that appears to
    be wanted/needed.

    Anton, do you want to take on mixing the zone into ->flags folding with
    your approach?
