I had been hoping to at least get the following in or checked out before
marking as not preliminary:

semaphores - patch series has one regression, but I would have liked it
merged and turned off

RC6 well tested - I am not sure what the state of our HW is in this
regard. I was told the HW we have doesn't support it, but I haven't
tried.

RPS - see RC6

4G GGTT - I guess this is currently blocked on PPGTT, which is
unfortunate. I can live without this for non-preilm.


I've been trying my best to keep the bug count low, and it has been
pretty good thanks to you and Paulo - so I think it should be safe
enough to call the HW supported, even with my gripes above. So while I
prefer to get the stuff above in/tested, if you want to move ahead with
this, it's
