Pull drm updates from Dave Airlie:
"One of the smaller drm -next pulls in ages!

Ben (nouveau) has a rewrite in progress but we decided to leave it
stew for another cycle, so just some fixes from him.

- radeon: lots of documentation work, fixes, more ring and locking
changes, pcie gen2, more dp fixes.
- i915: haswell features, gpu reset fixes, /dev/agpgart removal on
machines that we never used it on, more VGA/HDP fix., more DP fixes
- drm core: cleanups from Daniel, sis 64-bit fixes, range allocator
colouring.

but yeah fairly quiet merge this time, probably because I missed half

drm: Add colouring to the range allocator

In order to support snoopable memory on non-LLC architectures (so that
we can bind vgem objects into the i915 GATT for example), we have to
avoid the prefetcher on the GPU from crossing memory domains and so
prevent allocation of a snoopable PTE immediately following an uncached
PTE. To do that, we need to extend the range allocator with support for
tracking and segregating different node colours.

This will be used by i915 to segregate memory domains within the GTT.

v2: Now with more drm_mm helpers and less driver interference.

Merge branch 'drm-core-next' of git://people.freedesktop.org/~airlied/linux

Pull main drm updates from Dave Airlie:
"This is the main merge window request for the drm.

It's big, but jam packed will lots of features and of course 0
regressions. (okay maybe there'll be one).

Highlights:

- new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
(qemu only). These drivers use the generic modesetting drivers.

- initial prime/dma-buf support for i915, nouveau, radeon, udl and
exynos

- switcheroo audio support: so GPUs with HDMI can turn off the sound
driver without crashing stuff.

- There are some patches drifting outside drivers/gpu into x86 and
EFI for better handling of multiple video adapters in Apple Macs,
they've got correct acks except one trivial fixup.

- Core:
edid parser has better DMT and reduced blanking support,
crtc properties,
plane properties,

- Drivers:
exynos: add 2D core accel support, prime support, hdmi features
intel: more Haswell support, initial Valleyview support, more
hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
cleanups and fixes
radeon: more HDMI audio support, improved GPU lockup recovery
support, remove nested mutexes, less memory copying on PCIE, fix
bus master enable race (kexec), improved fence handling
gma500: cleanups, 1080p support, acpi fixes
nouveau: better nva3 memory reclocking, kepler accel (needs
external firmware rip), async buffer moves on nv84+ hw.

I've some more dma-buf patches that rely on the dma-buf merge for vmap
stuff, and I've a few fixes building up, but I'd decided I'd better
get rid of the main pull sooner rather than later, so the audio guys
are also unblocked."

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."

drm/i915: Introduce for_each_ring() macro

In many places we wish to iterate over the rings associated with the
GPU, so refactor them to use a common macro.

Along the way, there are a few code removals that should be side-effect
free and some rearrangement which should only have a cosmetic impact,
such as error-state.

Note that this slightly changes the semantics in the hangcheck code:
We now always cycle through all enabled rings instead of
short-circuiting the logic.

v2: Pull in a couple of suggestions from Ben and Daniel for
intel_ring_initialized() and not removing the warning (just moving them
to a new home, closer to the error).

- gpu hangman, this also contains the reset fix for gen4
- rps sanity check from Chris - this papers over issues when the gpu fails
to clock up on snb/ivb, and it is shockingly easy to hit. The code
prints a big WARN backtrace and restores the hw to a sane state. The
real fix is still in the works.

Atm I'm aware of 2 regressions in -next:
- One of the gmbus patches (not gmbus itself) regressed lvds detection on
a MacbookPro. I've analyzed the bug already and I think I know what's
going on, patch is awaiting test feedback.
- Just today QA reported that DP on ilk regressed. That bug is fresh of
the press and still awaiting detailed logfiles and the bisect result.
The only thing that's clear atm is that -fixes works and -next doesn't.

drm/i915: remove do_retire from i915_wait_request

This originates from a hack by me to quickly fix a bug in an earlier
patch where we needed control over whether or not waiting on a seqno
actually did any retire list processing. Since the two operations aren't
clearly related, we should pull the parameter out of the wait function,
and make the caller responsible for retiring if the action is desired.

The only function call site which did not get an explicit retire_request call
(on purpose) is i915_gem_inactive_shrink(). That code was already calling
retire_request a second time.
