Merge tag 'iommu-updates-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu into next

Pull IOMMU updates from Joerg Roedel:
 "The changes include:

   - a new IOMMU driver for ARM Renesas SOCs

   - updates and fixes for the ARM Exynos driver to bring it closer to a
     usable state again

   - convert the AMD IOMMUv2 driver to use the mmu_notifier->release
     call-back instead of the task_exit notifier

   - random other fixes and minor improvements to a number of other
     IOMMU drivers"
