Linus Torvalds 0cc6f45cec Merge tag 'iommu-updates-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
 "Core:
   - IOMMU memory usage observability - This will make the memory used
     for IO page tables explicitly visible.
   - Simplify arch_setup_dma_ops()

  Intel VT-d:
   - Consolidate domain cache invalidation
   - Remove private data from page fault message
   - Allocate DMAR fault interrupts locally
   - Cleanup and refactoring

  ARM-SMMUv2:
   - Support for fault debugging hardware on Qualcomm implementations
   - Re-land support for the ->domain_alloc_paging() callback

  ARM-SMMUv3:
   - Improve handling of MSI allocation failure
   - Drop support for the "disable_bypass" cmdline option
   - Major rework of the CD creation code, following on directly from
     the STE rework merged last time around.
   - Add unit tests for the new STE/CD manipulation logic

  AMD-Vi:
   - Final part of SVA changes with generic IO page fault handling

  Renesas IPMMU:
   - Add support for R8A779H0 hardware

  ... and a couple smaller fixes and updates across the sub-tree"

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.
