The IVRS ACPI table specifies maximum address sizes for I/O virtual
addresses that can be handled by the IOMMUs in the system. Parse that
data from the IVRS header to provide aperture information for DMA
mappings and users of the iommu API.

Sebastian Ott (3):
  iommu/amd: Parse supported address sizes from IVRS
  iommu/amd: Restrict aperture for domains to conform with IVRS
  iommu/amd: Actually enforce geometry aperture
