Ben Skeggs sent in his Nouveau DRM driver changes for the drm-next tree of open-source NVIDIA driver improvements that will land in Linux 3.18.

With the DRM merge window now closing earlier in the cycle, David Airlie is cutting off new features for the next kernel merge window from landing into drm-next after -rc5 of the current kernel. Thus, this week is the cut-off for new DRM driver functionality aiming for Linux 3.18 with Linux 3.17-rc5 having been released. As such, Ben Skeggs sent in his big batch of Nouveau DRM improvements.

The Nouveau improvements for Linux 3.18 include various GT21x clocking improvements by Roy Spliet via his Nouveau re-clocking EVoC funding. Aside from Roy's work is also various bits of GeForce Kepler memory re-clocking work, but there's still at least one major bit still left that's preventing the Nouveau driver from re-clocking Kepler memory to its higher rated frequencies. Additionally, Nouveau in Linux 3.18 has fan control improvements, Kepler HDMI info frame fixes, DisplayPort audio handling, and L2 cache + CBC improvements.

This batch of Nouveau 3.18 changes were pulled today via this pull request.
