Merge tag 'iommu-updates-v4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: "The updates include: - rate limiting for the VT-d fault handler - remove statistics code from the AMD IOMMU driver. It is unused and should be replaced by something more generic if needed - per-domain pagesize-bitmaps in IOMMU core code to support systems with different types of IOMMUs - support for ACPI devices in the AMD IOMMU driver - 4GB mode support for Mediatek IOMMU driver - ARM-SMMU updates from Will Deacon: - support for 64k pages with SMMUv1 implementations (e.g MMU-401) - remove open-coded 64-bit MMIO accessors - initial support for 16-bit VMIDs, as supported by some ThunderX SMMU implementations - a couple of errata workarounds for silicon in the field - various fixes here and there" * tag 'iommu-updates-v4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (44 commits) iommu/arm-smmu: Use per-domain page sizes. iommu/amd: Remove statistics code iommu/dma: Finish optimising higher-order allocations iommu: Allow selecting page sizes per domain iommu: of: enforce const-ness of struct iommu_ops iommu: remove unused priv field from struct iommu_ops iommu/dma: Implement scatterlist segment merging iommu/arm-smmu: Clear cache lock bit of ACR iommu/arm-smmu: Support SMMUv1 64KB supplement iommu/arm-smmu: Decouple context format from kernel config iommu/arm-smmu: Tidy up 64-bit/atomic I/O accesses io-64-nonatomic: Add relaxed accessor variants iommu/arm-smmu: Work around MMU-500 prefetch errata iommu/arm-smmu: Convert ThunderX workaround to new method iommu/arm-smmu: Differentiate specific implementations iommu/arm-smmu: Workaround for ThunderX erratum #27704 iommu/arm-smmu: Add support for 16 bit VMID iommu/amd: Move get_device_id() and friends to beginning of file iommu/amd: Don't use IS_ERR_VALUE to check integer values iommu/amd: Signedness bug in acpihid_device_group() ...
