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"
