Linus Torvalds e0fb1b3639 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
