The version offered by the core is ridiculously optimized and
does the same thing. So use it.

Daniel Vetter bd0c0ceef6 drm: move drm_getsarea into drm_bufs.c
It fiddles the sarea out of the maps which are also handled in
drm_bufs.c

With this drm_drv.c is a notch more legacy free.

David Herrmann 89c8233f82 drm/gem: simplify object initialization
drm_gem_object_init() and drm_gem_private_object_init() do exactly the
same (except for shmem alloc) so make the first use the latter to reduce
code duplication.

Also drop the return code from drm_gem_private_object_init(). It seems
unlikely that we will extend it any time soon so no reason to keep it
around. This simplifies code paths in drivers, too.

Last but not least, fix gma500 to call drm_gem_object_release() before
freeing objects that were allocated via drm_gem_private_object_init().
That isn't actually necessary for now, but might be in the future.

Highlights:
- follow-up refactoring after the shared dpll rework that landed in 3.11
- oddball prep cleanups from Ben for ppgtt
- encoder->get_config state tracking infrastructure from Jesse
- used by the experimental fastboot support from Jesse (disabled by
  default)
- make the error state file official and add it to our sysfs interface
  (Mika)
- drm_mm prep changes from Ben, prepares to embedd the drm_mm_node (which
  will be used by the vma rework later on)
- interrupt handling rework, follow up cleanups to the VECS enabling, hpd
  storm handling and fifo underrun reporting.
- Big pile of smaller cleanups, code improvements and related stuff.

Alex Deucher 444bddc4b9 drm/radeon/dpm: add debugfs support for RS780/RS880 (v3)
This allows you to look at the current DPM state via
debugfs.

Due to the way the hardware works on these asics, there's
no way to look up exactly what power state we are in, so
we make the best guess we can based on the current sclk.

v2: Anthoine's version
v3: fix ref div

One feature latecomer, I've forgotten to merge the patch to reeanble the
Haswell power well feature now that the audio interaction is fixed up.
Since that was the only unfixed issue with it I've figured I could throw
it in a bit late, and it's trivial to revert in case I'm wrong.

Otherwise all bug/regression fixes:
- Fix status page reinit after gpu hangs, spotted by more paranoid igt
  checks.
- Fix object list walking fumble regression in the shrinker (only the
  counting part, the actual shrinking code was correct so no Oops
  potential), from Xiong Zhang.
- Fix DP 1.2 bw limits (Imre).
- Restore legacy forcewake on ivb, too many broken biosen out there. We
  dump a warn though that recent userspace might fall over with that
  config (Guenter Roeck).
- Patch up the gen2 cs tlb w/a.
- Improve the fence coherency w/a now that we have a better understanding
  what's going on. The removed wbinvd+ipi should make -rt folks happy. Big
  thanks to Jon Bloomfield for figuring this out, patches from Chris.
- Fix write-read race when switching ring (Chris). Spotted with code
  inspection, but now we also have an igt for it.

There's an ugly regression we're still working on introduced between
3.10-rc7 and 3.10.0. Unfortunately we can't just revert the offender since
that one fixes another regression :( I've asked Steven to include my
-fixes branch into linux-next to prevent such fallout in the future,
hopefully.

Fix a warning from lockdep caused by calling flush_work() for

and reset_work upon successful radeon_irq_kms_init() completion
and thus perform hotplug flush_work only when rdev->irq.installed

If radeon_cs_parser_relocs fails ttm_eu_backoff_reservation doesn't get called.
This left open a bug where ttm_eu_reserve_buffers succeeded but the bo's were
not unlocked afterwards:

Daniel Vetter 50b44a449f drm/i915: clear DPLL reg when disabling i9xx dplls
Toghether with the hw state readout this should catch cases where we
don't properly updated the pll state (either in sw or hw). At least
for the shared dpll code the equivalent tricke helped a lot in
catching bugs.

Also rename the function prefix, it's not a generic piece of
infrastructure.

Daniel Vetter 3ad8a208ab drm/i915: Fix up cpt pixel multiplier enable sequence
Bspec for the "DPLL HDMI multiplier" field says:

"Restriction : The DPLL must be enabled and stable before setting these bits.
These bits must be programmed after DPLL_SEL is programmed."

There is apparently no restriction on programming the DPLL_SEL
register wrt the DPLL. So let's just move that up before we enable the
pch dpll.

v2: Rebase on top of the newly-colored BUG_ONs.

v3: Reinstate the lost write of the DPLL_MD register, spotted by Imre.
