Just minor stuff really, on vlv dp fix and two patches to tune down some
opregion sanity check. Plus MAINTAINERS update for the new git repo, which
is the only reason I've really bothered with this pull request.

drm/i915: demote opregion excessive timeout WARN_ONCE to DRM_INFO_ONCE

The WARN_ONCE is a bit too verbose, make it a DRM_INFO_ONCE.
While at it, add a #define for MAX_DSLP and make the message a bit more
informative.
v2: use DRM_INFO_ONCE, add MAX_DSLP, pimp the message.

Atm we setup the HW panel power sequencer logic both for eDP and DP
ports. On eDP we then go on and start the power on sequence and commence
with link training when it's ready. On DP we don't do the power on
sequencing but do the link training immediately. At this point the DP
PHY block gets stuck, since - supposedly - it is waiting for the power
on sequence to finish. The actual register write that seems to hold off
the PHY is PIPEX_PP_ON_DELAYS[Panel Control Port Select]. Writing here
a non-0 value eventually sets PIPEX_PP_STATUS[Require Asset Status] to
1 and blocks the PHY until the panel power on is ready.
Fix this by not doing any PP sequencing setup for DP ports.
Thanks to Ville Syrjälä, Jesse Barnes and Todd Previte for the help in
tracking this down.
Note that on older gmch platforms (where we have lvds instead of edp)
we've hacked around this by writing the magic ABCD unlock key to PP
registers, which disables the hw sanity checks.
For edp all platforms thus far had the pch split, with the edp port in
the north display complex and the PP registers on the pch the hw
sanity checks (expressed through the "Require Asset Status" bit) was
never functional, hence never a real issue.
This regression has been introduce in

Because we use a list_head in the bo to track it's position in a submit,
we need to serialize at a higher layer. Otherwise there are problems
when multiple contexts are SUBMIT'ing in parallel cmdstreams referencing
a shared bo.

Backport a few fixes found in the course of getting mdp5 working.
There is a window of time after pageflip is requested, before we
start scanning out the new fb (ie. while we are waiting for gpu).
During that time we need to continue holding a reference to the
still-current scanout fb, to avoid the backing gem bo's from being
destroyed.
Possibly a common mdp_crtc parent class could be useful to share
some of this logic between mdp4_crtc and mdp5_crtc. OTOH, this
all can be removed from the driver once atomic is in place, as
plane/crtc updates get deferred until all fb's are ready before
calling in to .page_flip(), etc.

A couple of vmwgfx fixes together with missing bits of legacy device
emulation to facilitate old user-space drivers on new devices.
The shader emulation bits are a bit large, but since they mostly touch the
new device code, regressions are unlikely. I figure the gain of having
this from the start clearly outweighs the risc of adding these bits at
this point.

When a context is first referenced in the command stream, make sure that all
scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that
all bound resources are put on the resource validate list.
This is needed for legacy emulation, since legacy user-space drivers will
typically not re-emit shader bindings. It also removes the requirement for
user-space drivers to re-emit render-target- and texture bindings.
Makes suspend and hibernate now also work with legacy user-space drivers on
guest-backed devices.
v2: Don't rebind on legacy devices.

Commit drm/ttm: ttm object security fixes for render nodes introduced a
regression where, if a TTM object was opened multiple times from the same
open file, the caller would spin uninterruptibly in the kernel.
Fix this.

If either idling channels or suspending the fence were to fail, the
display would never be resumed. Also if a client fails, resume the fence
(not functionally important, but it would potentially leak memory).

The DRM uses the adjusted mode to calculate constants for vblank
timestamping. Our encoder mode_fixup (usually) replaces this data
with our backend mode information, which doesn't have the needed
data filled in already.

Some DCE8 boards have a funky BlankCrtc table that results
in a timeout when trying to blank the display. The
timeout is harmless (all operations needed from the table
are complete), but wastes time and is confusing to users so
work around it.

The BlankCrtc table in some DCE8 boards has some
logic shortcuts for the vbios when this bit is set.
Clear it for driver use.

This is effectively a revert of 4573388c92ee60b4ed72b8d95b73df861189988c.
Forcing a display active when there is none causes problems with
dpm on some SI boards which results in improperly initialized
dpm state and boot failures on some boards. As for the bug commit
4573388c92ee tried to address, one can manually force the state to
high for better performance when using the card as a headless compute
node until a better fix is developed.

DCE5 and newer hardware only has 1 DAC. Use the correct
offset. This may fix display problems on certain board
configurations.

If we are not able to properly initialize one of the gpu
engines for buffer paging, we limit vram to the size of
the cpu visible aperture. We generally either use the gfx
or dma engine to do this. Clean up the size limiting code
to only adjust the size based on what ring is selected
for buffer paging rather than making assumptions about which
engine is selected for paging.
