Merge tag 'iommu-updates-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull IOMMU updates from Joerg Roedel:
 "Slightly more changes than usual this time:

   - KDump Kernel IOMMU take-over code for AMD IOMMU. The code now tries
     to preserve the mappings of the kernel so that master aborts for
     devices are avoided. Master aborts cause some devices to fail in
     the kdump kernel, so this code makes the dump more likely to
     succeed when AMD IOMMU is enabled.

   - common flush queue implementation for IOVA code users. The code is
     still optional, but AMD and Intel IOMMU drivers had their own
     implementation which is now unified.

   - finish support for iommu-groups. All drivers implement this feature
     now so that IOMMU core code can rely on it.

   - finish support for 'struct iommu_device' in iommu drivers. All
     drivers now use the interface.

   - new functions in the IOMMU-API for explicit IO/TLB flushing. This
     will help to reduce the number of IO/TLB flushes when IOMMU drivers
     support this interface.

   - support for mt2712 in the Mediatek IOMMU driver

   - new IOMMU driver for QCOM hardware

   - system PM support for ARM-SMMU

   - shutdown method for ARM-SMMU-v3

   - some constification patches

   - various other small improvements and fixes"
