[PATCH v2 00/19][PULL REQUEST] Intel IOMMU updates for v7.3

Hi Joerg,

The following changes are queued for v7.3-rc1. This update introduces
new features, quick fixes and several refactorings, including:

- Consolidation of complex enablement logic into a clean, priority-based
  state machine.
- Support for the DMA_REMAP_OPT_OUT flag from the VT-d v5.2
  specification.
- An update to cache_tag_flush_devtlb_psi() to use full-range constants
  instead of modifying shared variables for CACHE_TAG_NESTING_DEVTLB.
- A fix for the UCTP context-table slot when copying root entries.
- Fixes for several pre-existing issues reported by Sashiko.
- General code cleanup and refinement.

These patches are based on v7.2-rc6. The full series is also available
on GitHub:

https://github.com/LuBaolu/intel-iommu/commits/iommu/vt-d/next

Please consider pulling this series into the iommu/vt-d branch.

Change log:

v2:
 - Sashiko reported a critical issue in the previous PATCH 16/20. Remove
   that patch from this series. It requires more investigation time and
   will be submitted as a separate patch.
 - Add comments to the commit message of PATCH 03/20.

v1: https://lore.kernel.org/linux-iommu/[email protected]/

Best regards,
baolu
