run queue:
A set of entities scheduling commands for the same ring. It
implements the scheduling policy that selects the next entity to
emit commands from.
entity:
A scheduler entity is a wrapper around a job queue or a group of
other entities. This can be used to build hierarchies of entities.
For example all job queue entities belonging to the same process
may be placed in a higher level entity and scheduled against other
process entities.
Entities take turns emitting jobs from their job queue to the
corresponding hardware ring, in accordance with the scheduler policy.

The comment is misleading and incorrect, remove it.
Printing the id is completely meaningless and this practice
can cause a race conditions on command submission.
The flags and hangs fields are completely unused.
Give all fields a common indentation.

CGS (Common Graphics Services) is an AMD cross component
abstraction layer to designed to better encapsulate
specific IP block drivers so different teams can effectively
work on differnet IP block drivers independently. It provides
a common interface for things like accessing registers,
allocating GPU memory, and registering interrupt sources.
The plan is to eventually move more and more IP drivers to
this interface. The first user is the ACP IP driver.

A couple of fixes from the previous pull request as well as gl3 support.
There is one drm core change, an export of a previously private function.
Take 2 implementing screen targets, this time with the fbdev code adjusted
accordingly.
Also there is an implementation of register-driven command buffers, that
overrides the FIFO ring for command processing. It's needed for our upcoming
hardware revision.

drm/tegra: Changes for v4.3-rc1
There are a bunch of non-critical fixes here that I've collected over
the past few months, but the biggest part is Tegra210 support, in the
DC, DSI and SOR/HDMI drivers.
Also this finally restores DPMS with atomic mode-setting, something
that has been broken since the conversion and which I had originally
expected to take far less longer to fix.
