Shouldn't I also revert it in 4.9.y?

Yes, of course. Sorry. Somehow 4.9 keeps slipping my mind :-(.

NB there's certainly a dependency of some kind between this series and Christoph's swiotlb rework, which preceded it just a little, so I'm not at all surprised it can't be backported to the beginning of time without also pulling a pile of other changes.
Thank you both for taking care of this revert.
