Merge remote branch 'nouveau/drm-nouveau-next' of ../drm-nouveau-next into drm-core-next 

* 'nouveau/drm-nouveau-next' of ../drm-nouveau-next: (93 commits)
  drm/nv50: fix a couple of vm init issues
  drm/nv04-nv40: Fix up PCI(E) GART DMA object bus address calculation.
  drm/nouveau: kick vram functions out into an "engine"
  drm/nouveau: allow gpuobj vinst to be a virtual address when necessary
  drm/nv50: tidy up PCIEGART implementation
  drm/nv50: enable non-contig vram allocations where requested
  drm/nv50: enable 4KiB pages for small vram allocations
  drm/nv50: implement global channel address space on new VM code
  drm/nv50: implement BAR1/BAR3 management on top of new VM code
  drm/nv50: import new vm code
  drm/nv50: implement custom vram mm
  drm/nouveau: Avoid potential race between nouveau_fence_update() and context takedown.
  drm/nouveau: fix use of drm_mm_node in semaphore object
  drm/nouveau: wrap calls to ttm_bo_validate()
  drm/nouveau: no need to zero dma objects, we fill them completely anyway
  drm/nouveau: introduce a util function to wait on reg != val
  drm/nouveau: implicitly insert non-DMA objects into RAMHT
  drm/nouveau: make fifo.create_context() responsible for mapping control regs
  drm/nouveau: Spin for a bit in nouveau_fence_wait() before yielding the CPU.
  drm/nouveau: Use WC memory on the AGP GART.
