    Should we disable the warning that the nopage path gives if tasks are
    frozen? I'm in two minds - if you get problems as a result, it might
    help to diagnose them. On the other hand, you don't want tons of
    warnings due to the hibernation code trying to allocate memory it can't
    get. In TuxOnIce, I currently do all allocations with __GFP_NOWARN.
