Implement the virtio-iommu driver, following specification v0.9 [1]. Only minor changes since v5 [2]. I fixed issues reported by Michael and added tags from Eric and Bharat. Thanks! You can find Linux driver and kvmtool device on v0.9 branches [3], module and x86 support on virtio-iommu/devel. Also tested with Eric's QEMU device [4]. [1] Virtio-iommu specification v0.9, sources and pdf

Implement the virtio-iommu driver, following specification v0.8 [1]. Changes since v3 [2]: * Rebase onto v4.20-rc2. Patch 3 now touches drivers/of/base.c instead of drivers/pci/of.c, since the map_rid() function has moved. * Removed the request timeout, that depended on DEBUG. * Other small fixes addressing comments on v3. You can find Linux driver and kvmtool device on my virtio-iommu/v0.8.1
