Since commit "support gmap page tables with less than 5 levels" we can do better. Having more than 4 TB might be useful for some testing scenarios, so let's just limit ourselves to 16TB guest size. Having more than that is totally untested as I do not have enough swap space/memory. We continue to allow ucontrol the full size.
