? It's a small change, but it better fits with the arm64 terminology
("strongly ordered" is no longer used in the architecture).
If you're happy with that, I can make the change and queue this patch
for 5.4.
I'm fine with the change, but you really need this series as base,
as there is no pgprot_dmacoherent before the series. So I think I'll
have to queue it up if we want it for 5.4, and I'll need a few more
reviews for the other patches in this series first.
