IOMMU Updates for Linux v4.7
The updates include:
* Rate limiting for the VT-d fault handler
* Remove statistics code from the AMD IOMMU driver. It is unused
and should be replaced by something more generic if needed
* Per-domain pagesize-bitmaps in IOMMU core code to support
systems with different types of IOMMUs
* Support for ACPI devices in the AMD IOMMU driver
* 4GB mode support for Mediatek IOMMU driver
* ARM-SMMU updates from Will Deacon:
- Support for 64k pages with SMMUv1 implementations
(e.g MMU-401)
- Remove open-coded 64-bit MMIO accessors
- Initial support for 16-bit VMIDs, as supported by some
ThunderX SMMU implementations
- A couple of errata workarounds for silicon in the
field
* Various fixes here and there
