** Summary changed:

- Backport more recent driver for Skylake graphics hardware
+ Backport more recent driver for Skylake and Cherryview graphics hardware

** Description changed:

- We need to support Skylake (SKL) graphics in vivid, but the kernel
- driver is not fresh enough for proper support.
+ We need to support Skylake (SKL) and Cherryview (CHV) graphics in vivid,
+ but the kernel driver is not fresh enough for proper support.
  
  For the kernel the plan is to provide a separate driver module
- (i915_skl) like for Haswell in quantal and Broadwell in trusty. The i915
- driver in 3.19 is buggy and lacking features for SKL, so pulling the
- driver from current drm-intel-next-queued branch would provide what'll
- end up in 3.21. The i915 drivers will be modified so that only i915_skl
- loads on SKL machines, and only there. The driver will get further
- updates along the way, and possibly also rebased to a later kernel
- release.
