Three changes for the Armada DRM driver:
1. Add back the flags which tell the DRM core that we can do vblank. This
was removed in error during the recent restructuring, and came to light
while trying textured Xv rendering.
2. Fixing a refcount leak with Xv overlay.
3. As per recent discussion, the drm_vblank_pre_modeset() calls can cause
deadlock with other changes to generic code. This change prevents those
deadlocks by switching to the drm_crtc_vblank_*() calls instead.

The binary driver modifies the default context to have this value, rather

A refcounting leak was found of the original frame buffer attached to
the CRTC when using the page_flip ioctl, resulting in the frame buffer
never being freed.
This was not obvious initially, as if the page flip subsequently
re-attaches the original frame buffer, the refcounts will be balanced.
However, if the original frame buffer is freed, then it will be leaked.
Fix this by ensuring that we take a reference on the incoming fb, but
rely on the queued work to drop that ref count.

The radeon driver uses placement range restrictions for several reasons,
in particular to make sure BOs in VRAM can be accessed by the CPU, e.g.
during a page fault.
Without this change, TTM could evict other BOs while trying to satisfy
the requested placement, even if the evicted BOs were outside of the
requested placement range. Doing so didn't free up any space in the
requested placement range, so the (potentially high) eviction cost was
incurred for no benefit.
Nominating for stable because radeon driver changes in 3.17 made this
much more noticeable than before.

drm/i915: rework digital port IRQ handling (v2)
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=83175
Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com>

On CHV the display DDC pins may be muxed to an alternate function if
there's no need for DDC on a specific port, which is the case for eDP
ports since there's no way to plug in a DP++ HDMI dongle.
This causes problems when trying to determine if the port is present
since the the DP_DETECTED bit is the latched state of the DDC SDA pin
at boot. If the DDC pins are muxed to an alternate function the bit
may indicate that the port isn't present.
To work around this look at the VBT as well as the DP_DETECTED bit
to determine if we should attempt registering an eDP port. Do this
only for ports B and C since port D doesn't support eDP (no PPS/BLC).
In theory someone could also wire up a normal DP port w/o DDC lines.
That would just mean that simple DP++ HDMI dongles wouldn't work
on such a port. With this change we would still fail to register
such DP ports. But let's hope no one wires their board in such a way,
and if they do we can extend the VBT checks to cover normal DP ports
as well.

The old code has problems with the Dell MST monitors due to some
assumptions I made that weren't true.
I initially thought the Virtual Channel Payload IDs had to be in
the DPCD table in ascending order, however it appears that assumption
is bogus.
The old code also assumed it was possible to insert a member
into the table and it would move other members up, like it does
when you remove table entries, however reality has shown this
isn't true.
So the new code allocates VCPIs separate from entries in the payload
tracking table, and when we remove an entry from the DPCD table,
I shuffle the tracking payload entries around in the struct.
This appears to make VT switch more robust (still not perfect)
with an MST enabled Dell monitor.

TODO: Determine how best to scale "user" values to "hw" values, and
vice-versa, when the ranges are of different sizes. That would be a
buggy scenario even with this work-around.
The issue was introduced in the following (v3.17-rc1) commit:
6dda730 drm/i915: respect the VBT minimum backlight brightness
Note that for easier backporting this commit adds a duplicated macro.
A follow-up cleanup patch rectifies this for 3.18+
v2: (thanks to Chris Wilson) clarify commit message, use rounded division
macro
v3: -DIV_ROUND_CLOSEST() fails to build with CONFIG_X86_32=y. (Jani)
-Use DIV_ROUND_CLOSEST_ULL() instead. (Damien)
-v1 and v2 originally authored by Joe Konno.

Pull drm fixes from Dave Airlie:
"Nothing too major or scary.
One i915 regression fix, nouveau has a tmds regression fix, along with
a regression fix for the runtime pm code for optimus laptops not
restoring the display hw correctly"
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/nouveau: make sure display hardware is reinitialised on runtime resume
drm/nouveau: punt fbcon resume out to a workqueue
drm/nouveau: fix regression on original nv50 board
drm/nv50/disp: fix dpms regression on certain boards
drm/i915: Flush the PTEs after updating them before suspend
Adds an extra argument to radeon_bo_create, which is only used in radeon_prime.c.

final regression fix for 3.17.
* tag 'drm-intel-fixes-2014-10-02' of git://anongit.freedesktop.org/drm-intel:
drm/i915: Flush the PTEs after updating them before suspend
Linus commit 05c63c2ff2 modified the
runtime suspend/resume paths to skip over display-related tasks to
avoid locking issues on resume.
Unfortunately, this resulted in the display hardware being left in
a partially initialised state, preventing subsequent modesets from
completing.
This commit unifies the (many) suspend/resume paths, bringing back
display (and fbcon) handling in the runtime paths.
