Currently, all the new mappings will be read-write non-executable. Allow the

     Changes in v2:
         - Switch the runtime check to a BUG_ON()

Since you are at it, could you please also turn the other runtime check
few lines below into another BUG_ON (under MODIFY)?

I would prefer to keep the runtime check in MODIFY for now. It is not really critical and I plan to ditch create_xen_entries fairly soon.

This series is actually a preparatory for what's coming up.

Cheers,
