Merge branch 'drm-next-4.2-amdgpu' of git://people.freedesktop.org/~agd5f/linux into drm-next

This is the big pull request for amdgpu, the new driver for VI+ AMD
asics.  I currently supports Tonga, Iceland, and Carrizo and also
contains a Kconfig option to build support for CI parts for testing.

All major functionality is supported (displays, gfx, compute, dma,
video decode/encode, etc.).  Power management is working on Carrizo,
but is still being worked on for Tonga and Iceland.

* 'drm-next-4.2-amdgpu' of git://people.freedesktop.org/~agd5f/linux: (106 commits)
  drm/amdgpu: only support IBs in the buffer list (v2)
  drm/amdgpu: add vram_type and vram_bit_width for interface query (v2)
  drm/amdgpu: add ib_size/start_alignment interface query
  drm/amdgpu: add me/ce/pfp_feature_version interface query
  drm/amdgpu add ce_ram_size for interface query
  drm/amdgpu add max_memory_clock for interface query (v2)

  drm/amdgpu: remove all sh mem register modification in vm flush
  drm/amdgpu: rename GEM_OP_SET_INITIAL_DOMAIN -> GEM_OP_SET_PLACEMENT
  drm/amdgpu: fence should be added to shared slot
  drm/amdgpu: sync fence of clear_invalids (v2)
  drm/amdgpu: max_pde_used usage should be under protect
  drm/amdgpu: fix bug of vm_bo_map (v2)
  drm/amdgpu: implement the allocation range (v3)
