    Linus Torvalds authored
    Pull IOMMU updates from Joerg Roedel:
     "The updates are mostly about the x86 IOMMUs this time.
    
      Exceptions are the groundwork for the PAMU IOMMU from Freescale (for a
      PPC platform) and an extension to the IOMMU group interface.
    
      On the x86 side this includes a workaround for VT-d to disable
      interrupt remapping on broken chipsets.  On the AMD-Vi side the most
      important new feature is a kernel command-line interface to override
      broken information in IVRS ACPI tables and get interrupt remapping
      working this way.
    
      Besides that there are small fixes all over the place."
