Pull iommu updates from Joerg Roedel: - IOMMU Core changes: - Removal of aux domain related code as it is basically dead and will be replaced by iommu-fd framework - Split of iommu_ops to carry domain-specific call-backs separatly - Cleanup to remove useless ops->capable implementations - Improve 32-bit free space estimate in iova allocator - Intel VT-d updates: - Various cleanups of the driver - Support for ATS of SoC-integrated devices listed in ACPI/SATC table - ARM SMMU updates: - Fix SMMUv3 soft lockup during continuous stream of events - Fix error path for Qualcomm SMMU probe() - Rework SMMU IRQ setup to prepare the ground for PMU support - Minor cleanups and refactoring - AMD IOMMU driver: - Some minor cleanups and error-handling fixes - Rockchip IOMMU driver: - Use standard driver registration - MSM IOMMU driver: - Minor cleanup and change to standard driver registration - Mediatek IOMMU driver: - Fixes for IOTLB flushing logic * tag 'iommu-updates-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (47 commits) iommu/amd: Improve amd_iommu_v2_exit() iommu/amd: Remove unused struct fault.devid iommu/amd: Clean up function declarations iommu/amd: Call memunmap in error path iommu/arm-smmu: Account for PMU interrupts iommu/vt-d: Enable ATS for the devices in SATC table iommu/vt-d: Remove unused function intel_svm_capable() iommu/vt-d: Add missing "__init" for rmrr_sanity_check() iommu/vt-d: Move intel_iommu_ops to header file iommu/vt-d: Fix indentation of goto labels iommu/vt-d: Remove unnecessary prototypes iommu/vt-d: Remove unnecessary includes iommu/vt-d: Remove DEFER_DEVICE_DOMAIN_INFO iommu/vt-d: Remove domain and devinfo mempool iommu/vt-d: Remove iova_cache_get/put() iommu/vt-d: Remove finding domain in dmar_insert_one_dev_info() iommu/vt-d: Remove intel_iommu::domains iommu/mediatek: Always tlb_flush_all when each PM resume iommu/mediatek: Add tlb_lock in tlb_flush_all iommu/mediatek: Remove the power status checking in tlb flush all ...
