Merge tag 'iommu-updates-v3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU updates from Joerg Roedel:
 "This time the IOMMU updates contain a bunch of fixes and cleanups to
  various IOMMU drivers and the DMA debug code.  New features are the
  code for IRQ remapping support with the AMD IOMMU (preperation for
  that was already merged in the last release) and a debugfs interface
  to export some statistics in the NVidia Tegra IOMMU driver."
