Merge tag 'iommu-updates-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: "Nothing big this time. In particular: - Debugging code for Tegra-GART - Improvement in Intel VT-d fault printing to prevent soft-lockups when on fault storms - Improvements in AMD IOMMU event reporting - NUMA aware allocation in io-pgtable code for ARM - Various other small fixes and cleanups all over the place" * tag 'iommu-updates-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/io-pgtable-arm: Make allocations NUMA-aware iommu/amd: Prevent possible null pointer dereference and infinite loop iommu/amd: Fix grammar of comments iommu: Clean up the comments for iommu_group_alloc iommu/vt-d: Remove unnecessary parentheses iommu/vt-d: Clean up pasid quirk for pre-production devices iommu/vt-d: Clean up unused variable in find_or_alloc_domain iommu/vt-d: Fix iotlb psi missing for mappings iommu/vt-d: Introduce __mapping_notify_one() iommu: Remove extra NULL check when call strtobool() iommu/amd: Update logging information for new event type iommu/amd: Update the PASID information printed to the system log iommu/tegra: gart: Fix gart_iommu_unmap() iommu/tegra: gart: Add debugging facility iommu/io-pgtable-arm: Use for_each_set_bit to simplify code iommu/qcom: Simplify getting .drvdata iommu: Remove depends on HAS_DMA in case of platform dependency iommu/vt-d: Ratelimit each dmar fault printing
