Linus Torvalds f1c243fc78 IOMMU Updates for Linux v6.14
Including:
 
 	- Core changes:
 	  - PASID support for the blocked_domain.
 
 	- ARM-SMMU Updates:
 	  - SMMUv2:
 	    * Implement per-client prefetcher configuration on Qualcomm SoCs.
 	    * Support for the Adreno SMMU on Qualcomm's SDM670 SOC.
 	  - SMMUv3:
 	    * Pretty-printing of event records.
 	    * Drop the ->domain_alloc_paging implementation in favour of
 	      ->domain_alloc_paging_flags(flags==0).
 	  - IO-PGTable:
 	    * Generalisation of the page-table walker to enable external walkers
 	      (e.g. for debugging unexpected page-faults from the GPU).
 	    * Minor fix for handling concatenated PGDs at stage-2 with 16KiB pages.
 	  - Misc:
 	    * Clean-up device probing and replace the crufty probe-deferral hack
 	      with a more robust implementation of arm_smmu_get_by_fwnode().
 	    * Device-tree binding updates for a bunch of Qualcomm platforms.
 
 	- Intel VT-d Updates:
 	  - Remove domain_alloc_paging().
 	  - Remove capability audit code.
 	  - Draining PRQ in sva unbind path when FPD bit set.
 	  - Link cache tags of same iommu unit together.
 
 	- AMD-Vi Updates:
 	  - Use CMPXCHG128 to update DTE.
 	  - Cleanups of the domain_alloc_paging() path.
 
 	- RiscV IOMMU:
 	  - Platform MSI support.
 	  - Shutdown support.
 
 	- Rockchip IOMMU:
 	  - Add DT bindings for Rockchip RK3576.
 
 	- More smaller fixes and cleanups.

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.
