Slurped in this series, safe for the ssc fdi link oversubscription change, I'm not yet sure what I should do with that. For this one here, I'd _really_ like an i-g-t testcase that checks whether these workarounds are still set correctly after driver load (in the module reload test), after gpu resets (in the hangman) and after a suspend/resume (that testcase doesn't exists yet).
