IOMMU Updates for Linux v4.9 Including: * Support for interrupt virtualization in the AMD IOMMU driver. These patches were shared with the KVM tree and are already merged through that tree. * Generic DT-binding support for the ARM-SMMU driver. With this the driver now makes use of the generic DMA-API code. This also required some changes outside of the IOMMU code, but these are acked by the respective maintainers. * More cleanups and fixes all over the place.
