Pull IOMMU updates from Joerg Roedel: "This update comes with: - Support for lockless operation in the ARM io-pgtable code. This is an important step to solve the scalability problems in the common dma-iommu code for ARM - Some Errata workarounds for ARM SMMU implemenations - Rewrite of the deferred IO/TLB flush code in the AMD IOMMU driver. The code suffered from very high flush rates, with the new implementation the flush rate is down to ~1% of what it was before - Support for amd_iommu=off when booting with kexec. The problem here was that the IOMMU driver bailed out early without disabling the iommu hardware, if it was enabled in the old kernel - The Rockchip IOMMU driver is now available on ARM64 - Align the return value of the iommu_ops->device_group call-backs to not miss error values - Preempt-disable optimizations in the Intel VT-d and common IOVA code to help Linux-RT - Various other small cleanups and fixes" * tag 'iommu-updates-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (60 commits) iommu/vt-d: Constify intel_dma_ops iommu: Warn once when device_group callback returns NULL iommu/omap: Return ERR_PTR in device_group call-back iommu: Return ERR_PTR() values from device_group call-backs iommu/s390: Use iommu_group_get_for_dev() in s390_iommu_add_device() iommu/vt-d: Don't disable preemption while accessing deferred_flush() iommu/iova: Don't disable preempt around this_cpu_ptr() iommu/arm-smmu-v3: Add workaround for Cavium ThunderX2 erratum #126 iommu/arm-smmu-v3: Enable ACPI based HiSilicon CMD_PREFETCH quirk(erratum 161010701) iommu/arm-smmu-v3: Add workaround for Cavium ThunderX2 erratum #74 ACPI/IORT: Fixup SMMUv3 resource size for Cavium ThunderX2 SMMUv3 model iommu/arm-smmu-v3, acpi: Add temporary Cavium SMMU-V3 IORT model number definitions iommu/io-pgtable-arm: Use dma_wmb() instead of wmb() when publishing table iommu/io-pgtable: depend on !GENERIC_ATOMIC64 when using COMPILE_TEST with LPAE iommu/arm-smmu-v3: Remove io-pgtable spinlock iommu/arm-smmu: Remove io-pgtable spinlock iommu/io-pgtable-arm-v7s: Support lockless operation iommu/io-pgtable-arm: Support lockless operation iommu/io-pgtable: Introduce explicit coherency iommu/io-pgtable-arm-v7s: Refactor split_blk_unmap ...
