Sorry should have maybe been more clear, without patch 1 of this series
this won't work as the HAS_IOPORT config option is new and will be
missing otherwise. There's currently two options of merging this,
either all at once or first only patch 1 and then the additional
patches per subsystem until finally the last patch can remove
inb()/outb() and friends when HAS_IOPORT is unset.

Thanks,
Niklas
