    Linus Torvalds authored
    Pull iommu updates from Joerg Roedel:
     - batched unmap support for the IOMMU-API
     - support for unlocked command queueing in the ARM-SMMU driver
     - rework the ATS support in the ARM-SMMU driver
     - more refactoring in the ARM-SMMU driver to support hardware
       implemention specific quirks and errata
     - bounce buffering DMA-API implementatation in the Intel VT-d driver
       for untrusted devices (like Thunderbolt devices)
     - fixes for runtime PM support in the OMAP iommu driver
     - MT8183 IOMMU support in the Mediatek IOMMU driver
     - rework of the way the IOMMU core sets the default domain type for
       groups. Changing the default domain type on x86 does not require two
       kernel parameters anymore.
     - more smaller fixes and cleanups
