Merge tag 'iommu-fixes-v6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu fixes from Joerg Roedel:
- Intel VT-d fixes for nested domain handling:
- Cache invalidation for changes in a parent domain
- Dirty tracking setting for parent and nested domains
- Fix a constant-out-of-range warning
- ARM SMMU fixes:
- Fix CD allocation from atomic context when using SVA with SMMUv3
- Revert the conversion of SMMUv2 to domain_alloc_paging(), as it
breaks the boot for Qualcomm MSM8996 devices
- Restore SVA handle sharing in core code as it turned out there are
still drivers relying on it
