Are these changes guaranteed to not change the addresses in some way?
We've had really subtle bugs with offsets added / not added in the past.

The point it that we can later remove that get_system_io() in one place, instead of many. Please add isa_io_address_space() in a separate patch.

Yes (modulo those subtle bugs). > We've had really subtle bugs with offsets added / not added in the past. Those were bugs in the implementation of the portio functions and the memory core, not the conversions IIRC.
