I don't see a doc update. We do have documentation (in
Documentation/s390/vfio-ccw.txt) in which the uapi interface with the
regions and their purpose/usage  is at least kind of explained. You are
changing this interface without updating the doc.

I would like to see documentation on this because I'm under the
impression either the design is pretty convoluted or I did not
get it at all.
