If you want to insist on something here it should be for this driver
to use the new generic page table code I've written.
Otherwise I don't see the point in trying to improve this in some
lesser way.
If this had come in a years time I would probably insist on that, but
right now it isn't merged yet and it will still be a little bit before
people have time to review it.
Perhaps a compromise where Benjamin comes with an iommupt format
header that works for this and we can progress this series and be
ready to swap it out down the road?
