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.
