I believe this is wrong. For XIP you need two things:
o the physical address and
o play nicely with other (possibly rw) users.
Your patch still allows a JFFS2 on the other partition, corrupting any
XIP pages AXFS has handed out. No cookies.
Is there a reason you haven't used point() and unpoint()? What is wrong
with those functions?
