- IOVA allocation optimisations and removal of unused code
 
 - Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the
   page-table of an IOMMU domain
 
 - Support for changing the default domain type in sysfs
 
 - Optimisation to the way in which identity-mapped regions are created
 
 - Driver updates:
   * Arm SMMU updates, including continued work on Shared Virtual Memory
   * Tegra SMMU updates, including support for PCI devices
   * Intel VT-D updates, including conversion to the IOMMU-DMA API
 
 - Cleanup, kerneldoc and minor refactoring

Pull IOMMU updates from Will Deacon:
 "There's a good mixture of improvements to the core code and driver
  changes across the board.

  One thing worth pointing out is that this includes a quirk to work
  around behaviour in the i915 driver (see 65f746e828 ("iommu: Add
  quirk for Intel graphic devices in map_sg")), which otherwise
  interacts badly with the conversion of the intel IOMMU driver over to
  the DMA-IOMMU APU but has being fixed properly in the DRM tree.

  We'll revert the quirk later this cycle once we've confirmed that
  things don't fall apart without it.

  Summary:

   - IOVA allocation optimisations and removal of unused code

   - Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the
     page-table of an IOMMU domain

   - Support for changing the default domain type in sysfs

   - Optimisation to the way in which identity-mapped regions are
     created

   - Driver updates:
       * Arm SMMU updates, including continued work on Shared Virtual
         Memory
       * Tegra SMMU updates, including support for PCI devices
       * Intel VT-D updates, including conversion to the IOMMU-DMA API

   - Cleanup, kerneldoc and minor refactoring"
