IOMMU Fixes for Linux v4.7-rc3 Three patches queued up: * Fix for ARM-SMMU to add a missing iommu-ops callback which is required by common iommu code * Fix for the rockchip iommu where the wrong MMUs got the commands * A regression fix for the Intel VT-d driver. The regression only showed up on X58 chipsets with more than one iommu. These chipsets seem to require that QI is enabled on all IOMMUs before it can be used.
