  - Merge "iommu/vt-d: Fix some macros that are incorrectly specified in intel-iommu"
  - iommu/vt-d: Fix some macros that are incorrectly specified in intel-iommu

BugLink: http://bugs.launchpad.net/bugs/1673538
    commit aaa59306b0b7e0ca4ba92cc04c5db101cbb1c096 upstream.

    Some of the macros are incorrect with wrong bit-shifts resulting in picking
    the incorrect invalidation granularity. Incorrect Source-ID in extended
    devtlb invalidation caused device side errors.

    Change the signed-off-by to special character to avoid mail spam.

    Fixes: 2f26e0a9 ("iommu/vt-d: Add basic SVM PASID support")
