Linus Torvalds 531d29b0b6 IOMMU Updates for Linux v5.10
Including:
 
 	- ARM-SMMU Updates from Will:
 
 	  - Continued SVM enablement, where page-table is shared with
 	    CPU
 
 	  - Groundwork to support integrated SMMU with Adreno GPU
 
 	  - Allow disabling of MSI-based polling on the kernel
 	    command-line
 
 	  - Minor driver fixes and cleanups (octal permissions, error
 	    messages, ...)
 
 	- Secure Nested Paging Support for AMD IOMMU. The IOMMU will
 	  fault when a device tries DMA on memory owned by a guest. This
 	  needs new fault-types as well as a rewrite of the IOMMU memory
 	  semaphore for command completions.
 
 	- Allow broken Intel IOMMUs (wrong address widths reported) to
 	  still be used for interrupt remapping.
 
 	- IOMMU UAPI updates for supporting vSVA, where the IOMMU can
 	  access address spaces of processes running in a VM.
 
 	- Support for the MT8167 IOMMU in the Mediatek IOMMU driver.
 
 	- Device-tree updates for the Renesas driver to support r8a7742.
 
 	- Several smaller fixes and cleanups all over the place.
