At least iova.o wants to go with it. That's one of the parts that is a
candidate for harmonisation across IOMMU implementations, either by
removing it or by having others use it too. It's how we allocate virtual
I/O address space.

I suspect the interrupt remapping support may well want to move with it
too. It's no more out-of-place in drivers/iommu than it is in
drivers/pci. And then you can certainly move dmar.o too.
