Merge branch 'linux-4.8' of git://github.com/skeggsb/linux into drm-next

Here's an initial drm-next pull for nouveau 4.8, highlights:
- GK20A/GM20B volt and clock improvements.
- Initial support for GP100/GP104 GPUs, GP104 will not yet support
acceleration due to NVIDIA having not released firmware for them as of yet.

* 'linux-4.8' of git://github.com/skeggsb/linux: (97 commits)
  drm/nouveau/bus: remove cpu_coherent flag
  drm/nouveau/ttm: remove special handling of coherent objects
  drm/nouveau: check for supported chipset before booting fbdev off the hw
