If you are asking why I have proposed this patchset, then the answer is simple, 1st I've tried to find a way to move internal i915 helper to core (see patch 7). Then I was looking for possible other users of this helper. And apparently there are many of them, patches 3-7 shows some.
You want me to take this through te locking tree (for the next cycle, not this one) where I normally take atomic things or does someone else want this?
If you could take it I will be happy. Regards Andrzej
