Update 2 the state of drm-next-4.6 and next steps

[Matthew Macy]

At least to some degree hw accelerated 3d works on the 4.6 i915 driver (which in principle supports up through Kaby lake - I don't yet have anything newer than Haswell).

I anticipate maintaining all the pieces: linuxkpi, drm, i915, amdgpu, amdkfd as ports for the foreseeable future to make maintenance and continued development simpler.

I hope to post a call for testers this weekend or early next week.

Cheers.
