    Linus Torvalds authored
    Pull IOMMU updates from Joerg Roedel:
     - big-endian support and preparation for defered probing for the Exynos
       IOMMU driver
     - simplifications in iommu-group id handling
     - support for Mediatek generation one IOMMU hardware
     - conversion of the AMD IOMMU driver to use the generic IOVA allocator.
       This driver now also benefits from the recent scalability
       improvements in the IOVA code.
     - preparations to use generic DMA mapping code in the Rockchip IOMMU
     - device tree adaption and conversion to use generic page-table code
       for the MSM IOMMU driver
     - an iova_to_phys optimization in the ARM-SMMU driver to greatly
       improve page-table teardown performance with VFIO
     - various other small fixes and conversions
