Is it possible for the page to be bigger than 4GB?  If so then yes you
might be chopping off high-order bits or something.

Anyway please send me this change as a separate patch with a changelog
explaining that you're avoiding the div etc.... I don't want to roll it
in with the other unrelated fix (which changes code that was never
upstream anyway).
