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
