[git pull] drm fixes

[Dave Airlie]

This is the nasty race condition fix from Thomas, I've been running it and 
playing with firefox a lot and haven't seen any side effects of it, we 
have positive feedback on it fixing the actual problem of up 1GB of memory 
leaked in 5-10s of scrolling in the pathalogical cases.

Dave.
