Linus Torvalds 612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux 
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

/*
* The following is some guesswork on how the TV encoder flicker
* filter/rescaler works:
*
* It seems to use some sort of resampling filter, it is controlled
* through the registers at NV_PTV_HFILTER and NV_PTV_VFILTER, they
* control the horizontal and vertical stage respectively, there is
* also NV_PTV_HFILTER2 the blob fills identically to NV_PTV_HFILTER,
* but they seem to do nothing. A rough guess might be that they could
* be used to independently control the filtering of each interlaced
* field, but I don't know how they are enabled. The whole filtering
* process seems to be disabled with bits 26:27 of PTV_200, but we
* aren't doing that.
*
* The layout of both register sets is the same:
*
* A: [BASE+0x18]...[BASE+0x0] [BASE+0x58]..[BASE+0x40]
* B: [BASE+0x34]...[BASE+0x1c] [BASE+0x74]..[BASE+0x5c]
*
* Each coefficient is stored in bits [31],[15:9] in two's complement
* format. They seem to be some kind of weights used in a low-pass
* filter. Both A and B coefficients are applied to the 14 nearest
* samples on each side (Listed from nearest to furthermost. They
* roughly cover 2 framebuffer pixels on each side). They are
* probably multiplied with some more hardwired weights before being
* used: B-coefficients are applied the same on both sides,
* A-coefficients are inverted before being applied to the opposite
* side.
*
* After all the hassle, I got the following formula by empirical
* means...
