Linus Torvalds 8e143b90e4 IOMMU Updates for Linux v4.21
Including (in no particular order):
 
 	- 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
