Jason Gunthorpe 2d76228195 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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
