Merge tag 'iommu-updates-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull iommu updates from Joerg Roedel:
 "This time with:

   - support for the generic PCI device alias code in x86 IOMMU drivers

   - a new sysfs interface for IOMMUs

   - preparations for hotplug support in the Intel IOMMU driver

   - change the AMD IOMMUv2 driver to not hold references to core data
     structures like mm_struct or task_struct.  Rely on mmu_notifers
     instead.

   - removal of the OMAP IOVMM interface, all users of it are converted
     to DMA-API now

   - make the struct iommu_ops const everywhere

   - initial PCI support for the ARM SMMU driver

   - there is now a generic device tree binding documented for ARM
     IOMMUs

   - various fixes and cleanups all over the place

  Also included are some changes to the OMAP code, which are acked by
  the maintainer"
