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.
