Merge tag 'drm-intel-next-2013-04-06' of git://people.freedesktop.org/~danvet/drm-intel into drm-next 

Daniel writes:
Since I expect Linus to open the merge window in about a week I guess this
is the last i915 feature pull for 3.10. Highlights:
Updated testing tree for -next. Highlights:
- Corner case fixes discovered with static analyzers (Damien).
- More fixes to combat unclaimed register errors on Haswell (Paulo).
- Some small fixes to the gpu turbo code (Rodrigo+Ben), Ben has more
  fixes for overclocking support pending.
- More prep work for fastboot from Chris.
- VT-switchless suspend/resume from Jesse.
- The prep work of Egbert Eich's hpd irq storm handling. Hopefully we can
  squeeze in the actual storm handling code for 3.10 ...
- More convenience helpers for Imre's sg iterator. Core parts acked by
  Andrew Morton.
- A bit of backlight code cleanup from Jani.
- Fixed ilk gpu reset (Jesse).
- Reduced color range handling fixes for VLV (Ville).

The big item here is though the introduction of pipe_config to properly
pre-compute the desired modeset state before touching the hw. Together
with some very basic support to read out the current config from the hw
and compare the state with the sw tracking. This is all prep work for more
reliable fastboot, atomic modesets and other cool features. Stuff
converted to the new world includes:
- Most simple pipe attributes (reduce color range, pixel multiplier).
- Pipe bpp/dither handling.
- Some convenience flags like ->has_pch_encoder to simplify the code flow.
- (Almost) DP clock handling, had to be reverted since part of a prep
  patch was lost in rebasing ...
Expect a lot of patches for this throughout 3.11, there's tons of work
till we have all state properly tracked for fastbooting to woExpect a lot
of patches for this throughout 3.11, there's tons of work till we have all
state properly tracked for fastbooting to work.

For 3.10 I have a bunch of fixes queued up and I plan to send them all out
at the end of this week. I need to shuffle patches in my -next queue a bit
so that we don't but feature-y stuff in there, too. The main thing I'd
like to sneak in is Egbert's hpd irq storm handling, which should be
pretty low-risk since all the infrastructure work has landed already. I
also have the oops fix pending, but that only mustered review before the
w/e and giving how hairy that part of our modeset code is, I want to give
it some more testing before forwarding.

Note: annarchy.fd.o seems to run out of disk space, so couldn't push the
usual for-airlied branch. Tag should work though.

Note 2: I've had to do a backmerge since conflicts grew too ugly, but the
upstream -rc I've backmerged is already in your drm-next.
