[PATCH for 8.0 0/2] virtio-iommu: Fix Replay

[Eric Auger]

When assigning VFIO devices protected by a virtio-iommu we need to replay
the mappings when adding a new IOMMU MR and when attaching a device to
a domain. While we do a "remap" we currently fail to first unmap the
existing IOVA mapping and just map the new one. With some device/group
topology this can lead to errors in VFIO when trying to DMA_MAP IOVA
ranges onto existing ones.

Eric Auger (2):
  virtio-iommu: Add unmap on virtio_iommu_remap()
  virtio-iommu: Fix replay on device attach
