Linus Torvalds eec91e22fe IOMMU Updates for Linux v6.12
Including:
 
 	- Core changes:
 	  - Allow ATS on VF when parent device is identity mapped.
 	  - Optimize unmap path on ARM io-pagetable implementation.
 	  - Use of_property_present().
 
 	- ARM-SMMU changes:
 	  - SMMUv2:
 	    - Devicetree binding updates for Qualcomm MMU-500 implementations.
 	    - Extend workarounds for broken Qualcomm hypervisor to avoid
 	      touching features that are not available (e.g. 16KiB page
 	      support, reserved context banks).
 	  - SMMUv3:
 	    - Support for NVIDIA's custom virtual command queue hardware.
 	    - Fix Stage-2 stall configuration and extend tests to cover this
 	      area.
 	    - A bunch of driver cleanups, including simplification of the
 	      master rbtree code.
 	  - Plus minor cleanups and fixes across both drivers.
 
 	- Intel VT-d changes:
 	  - Retire si_domain and convert to use static identity domain.
 	  - Batched IOTLB/dev-IOTLB invalidation.
 	  - Small code refactoring and cleanups.
 
 	- AMD-Vi changes:
 	  - Cleanup and refactoring of io-pagetable code.
 	  - Add parameter to limit the used io-pagesizes.
 	  - Other cleanups and fixes.
