I'm not sure it's worth going that far -- it's not very likely that
anyone will be running on a machine with > 2^64 bytes of memory any
time soon, let alone registering 2^64 bytes of physically contiguous
memory in a memory region.

But on the other hand, if we're going to touch that code, there's no
reason to impose an arbitrary limit.  So I guess converting to
page_shift does make sense.
