    We still have 1000-odd places which do things like

    schedule_timeout(HZ/10);

    which will now involve a runtime divide. The propagation of msleep() and
    ssleep() will reduce that a bit, but not much.

    It's so simple to turn all those into compile-time divides that we may as
    well do it.
