[PATCH v6 0/7] virtio-iommu: Add ACPI support (x86 part) |

Allow instantiating a virtio-iommu device on ACPI systems by adding a
Virtual I/O Translation table (VIOT). Enable x86 support for VIOT.
Changes since v5 [1]:
* Split the series into x86 and arm parts. This patchset contains only
the VIOT table (patch 1) and the x86 support.
* Rebased onto master to fix a merge conflict
* Added review and acks, thanks!
The boot-bypass series [2] isn't a hard requirement for this series but
will be needed for complete support. In the meantime, storage accessed
by firmware needs to bypass the IOMMU some other way, using either a
virtio-blk device without the iommu_platform property, or a bypass
bridge (docs/iommu-bypass.txt).
You can find a description of the VIOT table, which will be included in
next ACPI version, here: https://jpbrucker.net/virtio-iommu/viot/viot-v9.pdf
