Some straggling drm core patches

* 'topic/core-stuff' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/gem: Always initialize the gem object in object_init
  drm/edid: Populate picture aspect ratio for CEA modes
  drm/edid: parse the list of additional 3D modes
  drm/edid: split VIC display mode lookup into a separate function
  drm: Make the connector mode_valid() vfunc return a drm_mode_status enum

Just a single fix for sparse/smatch warnings introduced by the previous
vmwgfx-next pull.

At least drm/i915 expects that the obj->dev pointer is set even in
failure paths. Specifically when the shmem initialization fails we
call i915_gem_object_free which needs to deref obj->base.dev to get at
the slab pointer in the device private structure. And the shmem
allocation can easily fail when userspace is hitting open file limits.

Doing the structure init even when the shmem file allocation fails
prevents this Oops.

This is a regression from

New tree with the INFO ioctl merge fixed up.  This also adds a couple
of additional minor fixes.

A few more changes for 3.14, mostly just bug fixes.  Note that:
drm/radeon: add query to fetch the max engine clock.
will conflict with 3.13 final, but the fix is pretty obvious.

Pull request of 2014-01-17

Pull request for 3.14. One not so urgent fix, One huge device update.

The pull request corresponds to the patches sent out on dri-devel, except:
[PATCH 02/33], review tag typo pointed out by Matt Turner.
[PATCH 04/33], dropped. The new surface formats are never used.

The upcoming vmware svga2 hardware version 11 will introduce the concept
of "guest backed objects" or -resources. The device will in principle
get all
of its memory from the guest, which has big advantages from the device
point of view.

This means that vmwgfx contexts, shaders and surfaces need to be backed
by guest memory in the form of buffer objects called MOBs, presumably
short for MemoryOBjects, which are bound to the device in a special way.

This patch series introduces guest backed object support. Some new IOCTLs
are added to allocate these new guest backed object, and to optionally
provide
them with a backing MOB.

There is an update to the gallium driver that comes with this update, and
it will be pushed in the near timeframe presumably to a separate mesa branch
before merged to master.
