Steve Sistare 441e8106a2 vfio: interfaces to update vaddr
Define interfaces that allow the underlying memory object of an iova
range to be mapped to a new host virtual address in the host process:

  - VFIO_DMA_UNMAP_FLAG_VADDR for VFIO_IOMMU_UNMAP_DMA
  - VFIO_DMA_MAP_FLAG_VADDR flag for VFIO_IOMMU_MAP_DMA
  - VFIO_UPDATE_VADDR extension for VFIO_CHECK_EXTENSION

Unmap vaddr invalidates the host virtual address in an iova range, and
blocks vfio translation of host virtual addresses.  DMA to already-mapped
pages continues.  Map vaddr updates the base VA and resumes translation.
See comments in uapi/linux/vfio.h for more details.
