Merge branch 'for-airlied' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Daniel writes:
"The big ticket item here is the new i915 modeset infrastructure.
Shockingly it didn't not blow up all over the place (i.e. I've managed to
fix the ugly issues before merging). 1-2 smaller corner cases broke, but
we have patches. Also, there's tons of patches on top of this that clean
out cruft and fix a few bugs that couldn't be fixed with the crtc helper
based stuff. So more stuff to come ;-)

Also a few other things:
- Tiny fix in the fb helper to go through the official dpms interface
  instead of calling the crtc helper code.
- forcewake code frobbery from Ben, code should be more in-line with
  what Windows does now.
- fixes for the render ring flush on hsw (Paulo)
- gpu frequency tracepoint
- vlv forcewake changes to better align it with our understanding of the
  forcewake magic.
- a few smaller cleanups"

+ 2 fixes.
