It may be an egregious error to attempt to use addresses outside the
range of the pagetable format, but that still doesn't mean we should
merrily wreak havoc by silently mapping/unmapping whatever truncated
portions of them might happen to correspond to real addresses.
Add some up-front checks to sanitise our inputs so that buggy callers
don't invite potential memory corruption.
