The last pull I'd like to squeeze into 3.5, safe for the hsw stuff mostly
bugfixes:
- last few patches for basic hsw enabling (Eugeni, infoframe support by
 Paulo)
- Fix up infoframe support, we've hopefully squashed all the cargo-culting
 in there (Paulo). Among all the issues, this finally fixes some of the
 infoframe regressions seen on g4x and snb systems.
- Fixup sdvo infoframe support, this fixes a regression from 2.6.37.
- Correctly enable semaphores on snb, we've enabled it already for 3.5,
 but the dmar check was slightly wrong.
- gen6 irq fixlets from Chris.
- disable gmbus on i830, the hw seems to be simply broken.
- fix up the pch pll fallout (Chris & me).
- for_each_ring macro from Chris - I've figured I'll merge this now to
 avoid backport pain.
- complain when the rps state isn't what we expect (Chris). Note that this
 is shockingly easy to hit and hence pretty much will cause a regression
 report. But it only tells us that the gpu turbo state got out of whack,
 a problem we know off since a long time (it cause the gpu to get stuck a
 a fixed frequency, usually the lowest one). Chris is working on a fix,
 but we haven't yet found a magic formula that works perfectly (only
 patches that massively reduce the frequency of this happening).
- MAINTAINERS patch, I'm now officially the guy to beat up."
