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

Daniel Vetter wrote
First pull request for 3.5-next, slightly large than usual because new
things kept coming in since the last pull for 3.4.
Highlights:
- first batch of hw enablement for vlv (Jesse et al) and hsw (Eugeni). pci
 ids are not yet added, and there's still quite a few patches to merge
 (mostly modesetting). To make QA easier I've decided to merge this stuff
 in pieces.
- loads of cleanups and prep patches spurred by the above. Especially vlv
 is a real frankenstein chip, but also hsw is stretching our driver's
 code design. Expect more to come in this area for 3.5.
- more gmbus fixes, cleanups and improvements by Daniel Kurtz. Again,
 there are more patches needed (and some already queued up), but I wanted
 to split this a bit for better testing.
- pwrite/pread rework and retuning. This series has been in the works for
 a few months already and a lot of i-g-t tests have been created for it.
 Now it's finally ready to be merged.  Note that one patch in this series
 touches include/pagemap.h, that patch is acked-by akpm.
- reduce mappable pressure and relocation throughput improvements from
 Chris.
- mmap offset exhaustion mitigation by Chris Wilson.
- a start at figuring out which codepaths in our messy dri1/ums+gem/kms
 driver we actually need to support by bailing out of unsupported case.
 The driver now refuses to load without kms on gen6+ and disallows a few
 ioctls that userspace never used in certain cases. More of this will
 definitely come.
- More decoupling of global gtt and ppgtt.
- Improved dual-link lvds detection by Takashi Iwai.
- Shut up the compiler + plus fix the fallout (Ben)
- Inverted panel brightness handling (mostly Acer manages to break things
 in this way).
- Small fixlets and adjustements and some minor things to help debugging.

Regression-wise QA reported quite a few issues on ivb, but all of them
turned out to be hw stability issues which are already fixed in
drm-intel-fixes (QA runs the nightly regression tests on -next alone,
without -fixes automatically merged in). There's still one issue open on
snb, it looks like occlusion query writes are not quite as cache coherent
as we've expected. With some of the pwrite adjustements we can now
reliably hit this. Kernel workaround for it is in the works."
