I suppose it would=E2=80=A6 but it still changes the API (gotta put the = additional bits somewhere), at which point you might as well just make = it 64-bits and be done with it. Still mulling over what the best solution is=E2=80=A6 there=E2=80=99s = other problems with the way gpio_intr() works (it=E2=80=99s not really = suitable as-is for level-triggered sources), and so a bunch of tweaks = will be necessary. -- thorpej
