    Pull IOMMU updates from Joerg Roedel:
     "A few new features this merge-window.  The most important one is
      probably, that dma-debug now warns if a dma-handle is not checked with
      dma_mapping_error by the device driver.  This requires minor changes
      to some architectures which make use of dma-debug.  Most of these
      changes have the respective Acks by the Arch-Maintainers.
    
      Besides that there are updates to the AMD IOMMU driver for refactor
      the IOMMU-Groups support and to make sure it does not trigger a
      hardware erratum.
    
      The OMAP changes (for which I pulled in a branch from Tony Lindgren's
      tree) have a conflict in linux-next with the arm-soc tree.  The
      conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is
      deleted in the arm-soc tree.  It is safe to delete the file too so
      solve the conflict.  Similar changes are done in the arm-soc tree in
      the common clock framework migration.  A missing hunk from the patch
      in the IOMMU tree will be submitted as a seperate patch when the
      merge-window is closed."
