[PATCH 0/7] amd-iommu debug patches for 2.6.31

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

This patchset contains updates to the debugging code in the AMD IOMMU
driver for Linux. It introduces two additional features:

  * A new command line parameter to let the driver dump the parsed
    contents of the IVRS ACPI table to dmesg. This is a debug feature to
    make it easier to find the bug for problems reported to me
  * A new Kconfig entry to enable IOMMU stress testing code. I made this
    Kconfig entry generic because other IOMMU implementations may pick
    this up as well.

Please review.
