I've just added this to my 3.15 queue, but it looks like Linus is going to tag 3.15 tomorrow and Dave already send out his most likely last pull request.
Going to send out another pull request in the evening if I can get the VM crashes resolved as well, but I doubt it will be included.
Since Linus is playing with the merge window overlap, I've taken this patch into my -fixes to send to him for the final one.
Please try and get a radeon tree asap for -next.
Dave.
