Really? This seems really odd. Usually we just don't build the code for any platform that doesn't have readq/writeq. Otherwise, shouldn't those arches just include this file themselves to keep everything working? Individual drivers shouldn't have to do this.
So, I'm not going to take this one just yet, sorry.
