[PATCH v3 0/7] Add virtio-iommu driver
Implement the virtio-iommu driver, following specification v0.8 [1].
Changes since v2 [2]:
* Patches 2-4 allow virtio-iommu to use the PCI transport, since QEMU
would like to phase out the MMIO transport. This produces a complex
topology where the programming interface of the IOMMU could appear
lower than the endpoints that it translates. It's not unheard of (e.g.
AMD IOMMU), and the
