Implement the virtio-iommu driver following version 0.6 of the specification [1]. Previous version, RFCv2, was sent in November [2]. This version addresses Eric's comments and changes the device number. (Since last week I also tested and fixed the probe/release functions, they now use devm properly.) I did not include ACPI support because the next IORT specifications isn't ready yet (even

Implement the virtio-iommu driver, following specification v0.9 [1]. Since v4 [2] I fixed the issues reported by Eric, and added Reviewed-by from Eric and Rob. Thanks! I changed the specification to fix one inconsistency discussed in v4. That the device fills the probe buffer with zeroes is now a "SHOULD" instead of a "MAY", since it's the only way for the driver to know
