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.

* tag 'drm-amdkfd-next-2015-07-20' of git://people.freedesktop.org/~gabbayo/linux:
  drm/amdkfd: Set correct doorbell packet type for Carrizo
  drm/amdkfd: Use generic defines in new amd headers

  drm/amdkfd: add support for VI in MQD manager
  drm/amdkfd: add CP HWS packet headers for VI
  drm/amdkfd: add supported CZ devices PCI IDs to amdkfd
  drm/amdkfd: Add dependency of DRM_AMDGPU to Kconfig
  drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interface
  drm/amdgpu: add amdgpu <--> amdkfd gfx7 interface
  drm/amdgpu: Add H/W agnostic amdgpu <--> amdkfd interface
  drm/radeon: Modify kgd_engine_type enum to match CZ
