Linus Torvalds 1e0ea4dff0 IOMMU Updates for Linux v7.0
Including:
 
 	- Core changes:
 	  - Rust bindings for IO-pgtable code
 	  - IOMMU page allocation debugging support
 	  - Disable ATS during PCI resets
 
 	- Intel VT-d changes:
 	  - Skip dev-iotlb flush for inaccessible PCIe device
 	  - Flush cache for PASID table before using it
 	  - Use right invalidation method for SVA and NESTED domains
 	  - Ensure atomicity in context and PASID entry updates
 
 	- AMD-Vi changes:
 	  - Support for nested translations
 	  - Other minor improvements
 
 	- ARM-SMMU-v2 changes:
 	  - Configure SoC-specific prefetcher settings for Qualcomm's "MDSS".
 
 	- ARM-SMMU-v3 changes:
 	  - Improve CMDQ locking fairness for pathetically small queue sizes.
 	  - Remove tracking of the IAS as this is only relevant for AArch32 and
 	    was causing C_BAD_STE errors.
 	  - Add device-tree support for NVIDIA's CMDQV extension.
 	  - Allow some hitless transitions for the 'MEV' and 'EATS' STE fields.
 	  - Don't disable ATS for nested S1-bypass nested domains.
 	  - Additions to the kunit selftests.
