Merge tag 'drm-intel-next-2012-07-06' of git://people.freedesktop.org/~danvet/drm-intel into drm-next 

Daniel writes:
New pull for -next. Highlights:
- rc6/turbo support for hsw (Eugeni)
- improve corner-case of the reset handling code - gpu reset handling
  should be rock-solid now
- support for fb offset > 4096 pixels on gen4+ (yeah, you need some fairly
  big screens to hit that)
- the "Flush Me Harder" patch to fix the gen6+ fallout from disabling the
  flushing_list
- no more /dev/agpgart on gen6+!
- HAS_PCH_xxx improvements from Paulo
- a few minor bits&pieces all over, most of it in thew hsw code
