Merge tag 'drm-amdkfd-next-2015-07-20' of git://people.freedesktop.org/~gabbayo/linux into drm-next

- Add Carrizo support for amdkfd, using the new amdgpu driver as the relevant
  kgd. The support includes interfaces with amdgpu both for gfx7 (Kaveri) and
  gfx8 (Carrizo). However, gfx7 interface is used for debugging purposes only,
  so amdkfd defaults to using radeon when Kaveri is installed.

I would like to note that no new IOCTLs are being introduced, and there is no
change in the current IOCTLs, as they are suited both for gfx7 and gfx8.
