    That would be very helpful. That should cover the remaining (ab)users
    of PageReserved.

    It would probably be fastest to implement this with a page flag,
    however if swsusp and ioremap are the only users then it shouldn't
    be a problem to go through slower lookups (and this would remove the
    need for the PageValidRAM flag that I had worried about earlier).
