Subject: [git pull] IOMMU Updates for Linux v6.10
Hi Linus,
There is a small and easy to resolve conflict with these changes in
drivers/acpi/scan.c. Please take the version that comes from the iommu
tree. With this being said:
The following changes since commit a38297e3fb012ddfa7ce0321a7e5a8daeb1872b6:
Linux 6.9 (2024-05-12 14:12:29 -0700)
are available in the Git repository at:

Merge branches 'arm/renesas', 'arm/smmu', 'x86/amd', 'core' and 'x86/vt-d' into next (2024-05-13 14:06:54 +0200)
----------------------------------------------------------------
IOMMU Updates for Linux v6.10
Including:
- 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
- A couple smaller fixes and updates across the sub-tree
