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?
