I have a custom io-pgtable implementation that gets wired up based on an
IOMMU domain attribute, which is set by yet another custom DMA mapper.
My main goal is to give clients a way to specify the page table format
they want to use. It's a bit of a mess but hopefully I can clean it up
and send it out soon.
