Any comments?

Looks fine to me, but I don't think it's urgent and I already sent my
SMMU pull for 4.11. I'll send this as a fix after the merge window.

OK. Thank you.

I suspect we need something similar for io-pgtable-arm-v7s.c, too.

Agree. On the whole I will be able to make similar patch for arm-v7s,
but I won't be 100% sure
since I don't have any boards where arm-v7s compatible IOMMU installed.

Shall I make patch for arm-v7s too?

Yes, please. Robin seems to enjoy using short-descriptor, so he might
give it a spin for you if you ask nicely.
