See Section 14 of Documentation/SubmittingPatches. You should never add 
tags unless they came from the said person. The ACKs from Andi is fine, 
the one from Christoph is borderline but OK and the one from Matt is 
_not_ OK.

I can fix those up but I'll wait from an explicit ACK from Christoph first.
