Merge tag 'iommu-updates-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU upates from Joerg Roedel:
 "This time a few more updates queued up.

   - Rework VT-d code to support ACPI devices

   - Improvements for memory and PCI hotplug support in the VT-d driver

   - Device-tree support for OMAP IOMMU

   - Convert OMAP IOMMU to use devm_* interfaces

   - Fixed PASID support for AMD IOMMU

   - Other random cleanups and fixes for OMAP, ARM-SMMU and SHMOBILE
     IOMMU

  Most of the changes are in the VT-d driver because some rework was
  necessary for better hotplug and ACPI device support"
