I would strongly object to trying to share map_pages, unmap_pages,
iova_to_phys, free and other iommu pt related functions in some
limited way instead of helping on the much more complete iommu pt
work. Which is what I said to Will, but for some reason he suggested
it anyhow.

Sorry, but it doesn't make sense to complain about duplication in
drivers and then not help advance one of the biggest projects to
actually concretely and comprehensively address that duplication.
