Was waiting for Greg's staging-linus branch to contain the dependencies
so I could do a merge test before sending him the pull. Took a few
more days after that to get to it as busy week. Now done.

Pull request for a micro set including this one just gone to Greg.
Not rc2 time yet so plenty of time ;)

Thanks
