(the Linux include was actually not used it seems)

Sounds fine.

Sure. I was doing it bit by bit just so that it was reviewable that I
didn't miss anything or violently screw anything up. Plus, there were
things that should be changed in skiboot as well.

I'd go back and do a similar thing to skiboot to make them match again
though, having linux/opal-api.h match skiboot/opal.h would just cause
swearing fits :)
