Well, I've never learned how to write CDL, or how to submit patches, and
don't want to learn just for this, especially since I'm not the one who
needs it. However, I think all that's needed is an option that reconfigures
things never to mask FIQ. Perhaps someone else who actually finds a use for
this feature will do it.
