Merge branch 'for-airlied-next' of git://people.freedesktop.org/~mlankhorst/linux into drm-next

Merge the move to generic fences for TTM using drivers.

* 'for-airlied-next' of git://people.freedesktop.org/~mlankhorst/linux:
  drm/nouveau: use shared fences for readable objects
  drm/nouveau: Keep only a single list for validation.
  drm/ttm: use rcu in core ttm
  drm/vmwgfx: use rcu in vmw_user_dmabuf_synccpu_grab
  drm/radeon: use rcu waits in some ioctls
  drm/nouveau: use rcu in nouveau_gem_ioctl_cpu_prep
  drm/ttm: flip the switch, and convert to dma_fence
  drm/qxl: rework to new fence interface
  drm/nouveau: rework to new fence interface
  drm/vmwgfx: rework to new fence interface, v2
  drm/vmwgfx: get rid of different types of fence_flags entirely
  drm/radeon: use common fence implementation for fences, v4
  drm/ttm: kill off some members to ttm_validate_buffer
  drm/ttm: add interruptible parameter to ttm_eu_reserve_buffers
  drm/ttm: kill fence_lock
  drm/ttm: call ttm_bo_wait while inside a reservation
  drm/nouveau: require reservations for nouveau_fence_sync and nouveau_bo_fence
  drm/nouveau: add reservation to nouveau_gem_ioctl_cpu_prep

-/* QXL fencing-
-
-   When we submit operations to the GPU we pass a release reference to the GPU
-   with them, the release reference is then added to the release ring when
-   the GPU is finished with that particular operation and has removed it from
-   its tree.
-
-   So we have can have multiple outstanding non linear fences per object.
-
-   From a TTM POV we only care if the object has any outstanding releases on
-   it.
-
-   we wait until all outstanding releases are processeed.
-
-   sync object is just a list of release ids that represent that fence on
-   that buffer.
-
-   we just add new releases onto the sync object attached to the object.
-
-   This currently uses a radix tree to store the list of release ids.
-
-   For some reason every so often qxl hw fails to release, things go wrong.
