Series should still apply as is so I don't think there is need to 
re-send. It will only conflict if I get to merge the "Assorted 
intel_gpu_top improvements" series first, in which case I can resend.

Again, if you agree there is no need to spam the list with a re-send 
yet, review can continue against this version, and I will note to change 
the above patch prefixes while doing the other changes the review is 
bound to trigger.
