entity:
A scheduler entity is a wrapper around a job queue or a group of

Merge branch 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux into drm-next

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.

fixed indirect system calls on O32 but it also introduced a bug for MIPS64
