This pull request fixes memory leak issue in exynos_drm_open() and
multiplatform breakage for ipp/gsc. And also including some cleanups.

Compared to original fixes pull req that I sent yesterday, this adds
one more fix that I found for a synchronization issue which starts to
crop up when we use XA in DDX for 2d accel on 3d core.  In particular,
accelerating presentation blit triggers this problem.

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.

Merge tag 'vmwgfx-fixes-3.14-2014-02-05' of git://people.freedesktop.org/~thomash/linux into drm-next

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.

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.

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.
