#     Merge tag 'iommu-updates-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull IOMMU updates from Joerg Roedel:
#     
#      - Page table code for AMD IOMMU now supports large pages where smaller
#        page-sizes were mapped before. VFIO had to work around that in the
#        past and I included a patch to remove it (acked by Alex Williamson)
#     
#      - Patches to unmodularize a couple of IOMMU drivers that would never
#        work as modules anyway.
#     
#      - Work to unify the the iommu-related pointers in 'struct device' into
#        one pointer. This work is not finished yet, but will probably be in
#        the next cycle.
#     
#      - NUMA aware allocation in iommu-dma code
#     
#      - Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver
#     
#      - Scalable mode support for the Intel VT-d driver
#     
#      - PM runtime improvements for the ARM-SMMU driver
#     
#      - Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom
#     
#      - Various smaller fixes and improvements
#
