Merge tag 'iommu-updates-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull IOMMU updates from Will Deacon: "There's a good mixture of improvements to the core code and driver changes across the board. One thing worth pointing out is that this includes a quirk to work around behaviour in the i915 driver (see 65f746e8 ("iommu: Add quirk for Intel graphic devices in map_sg")), which otherwise interacts badly with the conversion of the intel IOMMU driver over to the DMA-IOMMU APU but has being fixed properly in the DRM tree. We'll revert the quirk later this cycle once we've confirmed that things don't fall apart without it. Summary: - IOVA allocation optimisations and removal of unused code - Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the page-table of an IOMMU domain - Support for changing the default domain type in sysfs - Optimisation to the way in which identity-mapped regions are created - Driver updates: * Arm SMMU updates, including continued work on Shared Virtual Memory * Tegra SMMU updates, including support for PCI devices * Intel VT-D updates, including conversion to the IOMMU-DMA API - Cleanup, kerneldoc and minor refactoring" * tag 'iommu-updates-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (50 commits) iommu/amd: Add sanity check for interrupt remapping table length macros dma-iommu: remove __iommu_dma_mmap iommu/io-pgtable: Remove tlb_flush_leaf iommu: Stop exporting free_iova_mem() iommu: Stop exporting alloc_iova_mem() iommu: Delete split_and_remove_iova() iommu/io-pgtable-arm: Remove unused 'level' parameter from iopte_type() macro iommu: Defer the early return in arm_(v7s/lpae)_map iommu: Improve the performance for direct_mapping iommu: avoid taking iova_rbtree_lock twice iommu/vt-d: Avoid GFP_ATOMIC where it is not needed iommu/vt-d: Remove set but not used variable iommu: return error code when it can't get group iommu: Fix htmldocs warnings in sysfs-kernel-iommu_groups iommu: arm-smmu-impl: Add a space before open parenthesis iommu: arm-smmu-impl: Use table to list QCOM implementations iommu/arm-smmu: Move non-strict mode to use io_pgtable_domain_attr iommu/arm-smmu: Add support for pagetable config domain attribute iommu: Document usage of "/sys/kernel/iommu_groups/<grp_id>/type" file iommu: Take lock before reading iommu group default domain type ...
