    Subject[135/264] iommu/amd: Fix wrong shift direction
    3.1-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Joerg Roedel <joerg.roedel@amd.com>

    commit fcd0861db1cf4e6ed99f60a815b7b72c2ed36ea4 upstream.

    The shift direction was wrong because the function takes a
    page number and i is the address is the loop.
