Mostly these are fixes, except for patches 4 and 8, which are the meat of this series and actually switching on the MC support. Can those be moved to the end? That also makes it easier to merge the earlier patches if some more work is needed for the MC part. I'm also not sure whether patches 4 and 8 shouldn't be a single patch, since patch 4 leaves the driver in an inconsistent state since it is missing the link validation code that patch 8 adds. Unless I missed something?
