However, the userspace nouveau-ddx needs to be aware if it is

drm/nouveau: Dis/Enable vblank irqs during suspend/resume.
Vblank irqs don't get disabled during suspend or driver
unload, which causes irq delivery after "suspend" or
driver unload, at least until the gpu is powered off.
This could race with drm_vblank_cleanup() in the case
of nouveau and cause a use-after-free bug if the driver
is unloaded.
More annoyingly during everyday use, at least on nv50
display engine (likely also others), vblank irqs are
off after a resume from suspend, but the drm doesn't
know this, so all vblank related functionality is dead
after a resume. E.g., all windowed OpenGL clients will
hang at swapbuffers time, as well as many fullscreen
clients in many cases. This makes suspend/resume useless
if one wants to use any OpenGL apps after the resume.
In Linux 3.16, drm_vblank_on() was added, complementing
the older drm_vblank_off() to solve these problems
elegantly, so use those calls in nouveaus suspend/resume
code.
For kernels 3.8 - 3.15, we need to cherry-pick the
drm_vblank_on() patch to support this patch.

As documented at:

NVIDIA were not able document the steps necessary to detect whether this
is required or not at this time. However, they did confirm that this
procedure is safe to perform unconditionally on GK104/6. GK107 does not
have the power gating feature, and it was recommended that we do not
perform these steps there as the effects were not verified.
The disable path is from observing the binary driver, and not
documented in the link above.

Revert "drm: drop redundant drm_file->is_master"
This reverts commit
48ba813701eb14b3008edefef4a0789b328e278c.
Thanks to Chris:
"drm_file->is_master is not synomous with having drm_file->master ==
drm_file->minor->master. This is because drm_file->master is the same
for all drm_files of the same generation and so when there is a master,
every drm_file believes itself to be the master. Confusion ensues and
things go pear shaped when one file is closed and there is no master
anymore."

drm/tegra: Changes for v3.17-rc1
Mostly some cleanup all over the place. Pitch alignment limitations of
the display controller are now honored and job submission is 64-bit
safe.
The SOR output (used for eDP) properly configures sync signal polarities
according to the display mode rather than hard-coding them to some value
and the number of bits per color is now taken from the panel rather than
hard-coded to properly support 24-bit vs. 18-bit panels.
The DSI controller now properly supports non-continuous clock mode.
GEM objects can now have their flags and tiling mode modified via IOCTLs
to allow buffers imported from Nouveau to be properly displayed. Newer
generations of the Tegra display controller can also detile block linear
buffers at scan-out time.
Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it
to be automatically loaded when built as a module.

drm/panel: Changes for v3.17-rc1
Panels can now be more finely controlled via .prepare() and .unprepare()
callbacks in addition to .enable() and .disable(). New kerneldoc details
what they are supposed to do and when they should be called.
The simple panel driver gained support for a couple of new panels and it
is now possible to specify additional delays during power up and power
down sequences if panels require it.
DSI devices can now advertise that they support non-continuous clock
mode which will allow DSI host controllers to disable the high speed
clock after transmissions to save power.
