This changes the layout for arm too, but that's fine. The only
thing to keep in mind is that while arm64 will have a single
64k page for its stack, arm will have 16 4k pages. If the number
of stack pages matters, then unit tests that want to work for
both arm and arm64, may need to avoid using more than one page,
even though the memory is there.
