$dayjob has had me very busy. Which is a good thing :-)

from the various subsystems so that we
can merge this as one bisectable branch.
Changes from v1:
- Explicitly mention page_aligned start assumption (Yann Droneaud)
- pick random pages vice random addresses (Yann Droneaud)
- catch range=0 last
- Add Ack for arm64 (Will Deacon)
