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?
