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.
