Yes, that's enough.
I _thought_ the AMD folks provided some tested-by's at some point in the past. But, maybe I'm confusing this for one of the other shared features. Either way, I'm sure no tested-by's were dropped on purpose.
I'm sure Rick is eager to trim down his series and this would be a great patch to drop. Does anyone want to make that easy for Rick?
