There are two issues I see with the design and I don't understand how
they are addressed:
1) On machines where the cache is responsible for handling ECC, how do you
prevent a user from trying to mount a device XIP, causing a data error and
a system crash?
2) How will this work with mfs and memory disks where you really want to
use XIP always but the pages are standard, managed RAM?
