This update is mostly about a workaround for BIOS problems with AMD IOMMU when
resuming from S3. The BIOS on an AMD IOMMU capable machine might be buggy so
that the IOMMU device is not re-enabled on resume. The patch from Matthew
implement a workaround for this problem by manually re-enabling an
re-programming the IOMMU device on resume. Please pull.

Joerg
