Please post and explain them here.  In general I think moving dma
ops and iommu implementations into modules is a bad idea, but I
don't want to reject the idea before seeing the code.  Or maybe
by looking at the user we can come up with an even better idea
to solve the original issue you're trying to solve, so please also
explain your rationale.
