    arm: revert MAXDSIZ change from 202aea9c82ea
    
    This imposes a fairly severe limitation on space available for mmap that
    was not noticed prior to commit. Unfixed mmap will only map from
    [data + MAXSIZE, end of user VA space], bringing the amount of usable space
    down way too low for non-trivial link jobs (for instance).
