Hi Joerg,

The following fixes have been queued for v6.7. They aim to:

- Do not support enforcing cache coherency for non-empty domains
- Avoid devTLB invalidation if iommu is off
- Disable PCI ATS in legacy passthrough mode
- Support non-PCI devices when clearing context
- Fix incorrect cache invalidation for mm notification
- Add MTL to quirk list to skip TE disabling
- Set variable intel_dirty_ops to static

Please consider them for the iommu/fix branch.

Best regards,
Lu Baolu
