[GIT PULL] AMD IOMMU updates for 2.6.28

[Joerg Roedel <joerg.roedel@amd.com>]

Hi Ingo,

please pull the updates for the AMD IOMMU driver for the 2.6.28 merge
window. Most of the patches had been sent to LKML for review and got
comments. One patch touches the GART driver and was added after an
objection with a patch previously in this series. Please pull.

  Ingo Molnar (1):
