======================================
IOMMU Updates for Linux v6.13:

Including:

	- Core Updates:
	  - Convert call-sites using iommu_domain_alloc() to more specific
	    versions and remove function.
	  - Introduce iommu_paging_domain_alloc_flags().
	  - Extend support for allocating PASID-capable domains to more
	    drivers.
	  - Remove iommu_present().
	  - Some smaller improvements.

	- New IOMMU driver for RISC-V.

	- Intel VT-d Updates:
	  - Add domain_alloc_paging support.
	  - Enable user space IOPFs in non-PASID and non-svm cases.
	  - Small code refactoring and cleanups.
	  - Add domain replacement support for pasid.

	- AMD-Vi Updates:
	  - Adapt to iommu_paging_domain_alloc_flags() interface and alloc V2
	    page-tables by default.
	  - Replace custom domain ID allocator with IDA allocator.
	  - Add ops->release_domain() support.
	  - Other improvements to device attach and domain allocation code
	    paths.

	- ARM-SMMU Updates:
	  - SMMUv2:
	    - Return -EPROBE_DEFER for client devices probing before their SMMU.
	    - Devicetree binding updates for Qualcomm MMU-500 implementations.
	  - SMMUv3:
	    - Minor fixes and cleanup for NVIDIA's virtual command queue driver.
	  - IO-PGTable:
	    - Fix indexing of concatenated PGDs and extend selftest coverage.
	    - Remove unused block-splitting support.

	- S390 IOMMU:
	  - Implement support for blocking domain.

	- Mediatek IOMMU:
	  - Enable 35-bit physical address support for mt8186.

	- OMAP IOMMU driver:
	  - Adapt to recent IOMMU core changes and unbreak driver.
