I hoped this could be an exception, it's easier to grok without the

Frankly this patch is hard to justify anyway - iommu-dma already has its
own reserved region handling, and there should be no need for external
callers to be poking into the innards provided the IOMMU driver reports
the correct reserved regions in the first place.
If the iommu-dma abstraction is not quite sufficient to actually convert
amd-iommu to use it properly, then we should improve the abstraction,
rather than just punching holes in it to merely poke renamed parts of
the existing amd-iommu logic into.
