They don't really care. iommu_get() et al. are convenience functions
which can and do return NULL when there's no I

good idea
- implementing features not used by Linux (e.g. interrupt remapping)
That being said, any feedback is welcome.
Thanks,

P.S.: I'd also like to thank Paul Brook for his help on figuring out
some aspects of the IOMMU layer.
