Subject: [PATCH 00/17] Convert TTM to the new fence interface.

This series applies on top of the driver-core-next branch of
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git

Before converting ttm to the new fence interface I had to fix some
drivers to require a reservation before poking with fence_obj.
After flipping the switch RCU becomes available instead, and
the extra reservations can be dropped again. :-)

I've done at least basic testing on all the drivers I've converted
at some point, but more testing is definitely welcomed!

Maarten Lankhorst (17):
      drm/ttm: add interruptible parameter to ttm_eu_reserve_buffers
      drm/ttm: kill off some members to ttm_validate_buffer
      drm/nouveau: add reservation to nouveau_gem_ioctl_cpu_prep
      drm/nouveau: require reservations for nouveau_fence_sync and nouveau_bo_fence
      drm/ttm: call ttm_bo_wait while inside a reservation
      drm/ttm: kill fence_lock
      drm/nouveau: rework to new fence interface
      drm/radeon: add timeout argument to radeon_fence_wait_seq
      drm/radeon: use common fence implementation for fences
      drm/qxl: rework to new fence interface
      drm/vmwgfx: get rid of different types of fence_flags entirely
      drm/vmwgfx: rework to new fence interface
      drm/ttm: flip the switch, and convert to dma_fence
      drm/nouveau: use rcu in nouveau_gem_ioctl_cpu_prep
      drm/radeon: use rcu waits in some ioctls
      drm/vmwgfx: use rcu in vmw_user_dmabuf_synccpu_grab
      drm/ttm: use rcu in core ttm
