[Intel-gfx] Updated -next

[Daniel Vetter]

Hi all,

I've pushed out a new -next and testing tree. Highlights:
- first batch of hsw enabling (Eugeni)
- first batch of vlv enabling (Jesse and others)
- a few cleanups spurred by the above items
- pwrite/pread rework and speedups
- less mappable pressure and reloc optimizations (Chris)
- mmap_offset exhaustion mitigation (Chris)
- more gmbus cleanups and fixes (Daniel Kurtz), now also enabled for gen2
- a start at figuring out what code of our gem+ums/kms/dri1 codebase is
  actually support by disallowing these ioctls

Happy testing!

Cheers, Daniel
