[SLOF] [PATCH slof v3 0/4] virtio: Enable iommu_platform=on

[Alexey Kardashevskiy]

This is my current queue of patches to enable IOMMU for virtio
which is going to be required for secure guests, and is a right
thing to do in general.

v3 changes 1/4 + few cleanups here and there.

In order to enable IOMMU, add this to a virtio-pci device:

-device virtio-blk-pci,iommu_platform=off,disable-modern=off,disable-legacy=on

Please comment and test. Thanks.
