Pull intel iommu updates from David Woodhouse:
"This adds "Shared Virtual Memory" (aka PASID support) for the Intel
IOMMU. This allows devices to do DMA using process address space,
translated through the normal CPU page tables for the relevant mm.
With corresponding support added to the i915 driver, this has been
tested with the graphics device on Skylake. We don't have the
required TLP support in our PCIe root ports for supporting discrete
devices yet, so it's only integrated devices that can do it so far"
