This should probably be called plain "pat" to mirror arch/x86/mm/pat.c "nopat" force off parameter. That by the way is an early_param which I guess this should then also be?

Either that or "pat={off,on,force}" to give space for other options... would mean keeping "nopat" around as an alias for now, though...

Yes, that would be nicer. As to the alias; "nopat" hasn't been in a released kernel yet so should be okay to do away with? It's not like it's in Documentation/kernel-parameters.txt or anything... ;-/

OK, just double-checked... since it's not in Linus we can still change it, and as so I'd suggest the pat= option.
