    Pull IOMMU updates from Joerg Roedel:
     "This time with bigger changes than usual:
    
       - A new IOMMU driver for the ARM SMMUv3.
    
         This IOMMU is pretty different from SMMUv1 and v2 in that it is
         configured through in-memory structures and not through the MMIO
         register region.  The ARM SMMUv3 also supports IO demand paging for
         PCI devices with PRI/PASID capabilities, but this is not
         implemented in the driver yet.
    
       - Lots of cleanups and device-tree support for the Exynos IOMMU
         driver.  This is part of the effort to bring Exynos DRM support
         upstream.
    
       - Introduction of default domains into the IOMMU core code.
    
         The rationale behind this is to move functionalily out of the IOMMU
         drivers to common code to get to a unified behavior between
         different drivers.  The patches here introduce a default domain for
         iommu-groups (isolation groups).
    
         A device will now always be attached to a domain, either the
         default domain or another domain handled by the device driver.  The
         IOMMU drivers have to be modified to make use of that feature.  So
         long the AMD IOMMU driver is converted, with others to follow.
    
       - Patches for the Intel VT-d drvier to fix DMAR faults that happen
         when a kdump kernel boots.
    
         When the kdump kernel boots it re-initializes the IOMMU hardware,
         which destroys all mappings from the crashed kernel.  As this
         happens before the endpoint devices are re-initialized, any
         in-flight DMA causes a DMAR fault.  These faults cause PCI master
         aborts, which some devices can't handle properly and go into an
         undefined state, so that the device driver in the kdump kernel
         fails to initialize them and the dump fails.
    
         This is now fixed by copying over the mapping structures (only
         context tables and interrupt remapping tables) from the old kernel
         and keep the old mappings in place until the device driver of the
         new kernel takes over.  This emulates the the behavior without an
         IOMMU to the best degree possible.
    
       - A couple of other small fixes and cleanups"
