Actually... Just mirroring the iommu_dma_strict value into
struct iommu_domain should solve all of that with very little
boilerplate code.

Yes, my initial thought was to directly replace the attribute with a
common flag at iommu_domain level, but since in all cases the behaviour
is effectively global rather than actually per-domain, it seemed
reasonable to take it a step further. This passes compile-testing for
arm64 and x86, what do you think?

It seems to miss a few bits, and also generally seems to be not actually
apply to recent mainline or something like it due to different empty
lines in a few places.

Let me know what you think of the version here:

I'll happily switch the patch to you as the author if you're fine with
that as well.
