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.

* 0xc{0,2}3c*, 0x60{1,3}3*, and 0x68{1,3}3d*
|
|
* in general, the set value of cr44 does not matter: reg access works as

* expected and values can be set for the appropriate head by using a 0x2000

|
* offset as required
|

* however:
|
|
* a) pre nv40, the head B range of PRMVIO regs at 0xc23c* was not exposed and
|
|
* cr44 must be set to 0 or 3 for accessing values on the correct head
|
|
* through the common 0xc03c* addresses
|
|
* b) in tied mode (4) head B is programmed to the values set on head A, and
|
|
* access using the head B addresses can have strange results, ergo we leave
|
|
* tied mode in init once we know to what cr44 should be restored on exit
|
|
*
|
|
* the owner parameter is slightly abused:
|
|
* 0 and 1 are treated as head values and so the set value is (owner * 3)
