Hi Linus,
Please note that the patch from the fixes branch included in this pull request
is already part of v6.19 as I did not re-create the merge commit on-top of
v6.19. With that in mind:
The following changes since commit 18f7fcd5e69a04df57b563360b88be72471d6b62:
Linux 6.19-rc8 (2026-02-01 14:01:13 -0800)
are available in the Git repository at:

----------------------------------------------------------------
IOMMU Updates for Linux v7.0
Including:
- Core changes:
- Rust bindings for IO-pgtable code
- IOMMU page allocation debugging support
- Disable ATS during PCI resets
- Intel VT-d changes:
- Skip dev-iotlb flush for inaccessible PCIe device
- Flush cache for PASID table before using it
- Use right invalidation method for SVA and NESTED domains
- Ensure atomicity in context and PASID entry updates
- AMD-Vi changes:
- Support for nested translations
- Other minor improvements
- ARM-SMMU-v2 changes:
- Configure SoC-specific prefetcher settings for Qualcomm's "MDSS".
- ARM-SMMU-v3 changes:
- Improve CMDQ locking fairness for pathetically small queue sizes.
- Remove tracking of the IAS as this is only relevant for AArch32 and
was causing C_BAD_STE errors.
- Add device-tree support for NVIDIA's CMDQV extension.
- Allow some hitless transitions for the 'MEV' and 'EATS' STE fields.
- Don't disable ATS for nested S1-bypass nested domains.
- Additions to the kunit selftests.
