Hmmm I now see why you added cpu_relax() at the top. Well, on Xen
cpu_relax is just a barrier. On Linux it is used to yield.
And that bit is worrying me.

Hi Sameer,
Given this is all Arm specific. I am not sure why people like Andrew,
Jan have been added.
Please use scripts/get_maintainers to find the list of maintainers per
patches and avoid to CC all of them on each patches.

This driver follows an approach similar to smmu driver. The intent here
is to reuse as much Linux code as possible.
- Glue code has been introduced to bridge the API calls.
- Called Linux functions from the Xen IOMMU function calls.
- Xen modifications are preceded by /*Xen: comment */
