Is this distinction ever useful?
The assumption that a pointer fits in a long is rather ingrained into Xen's
code base. Any attempt to remove that assumption is going to need some big
patches, and it's really not clear that we ought to care as I'm sure it's
true for any architecture we can conceive of caring one jot about.
