This is safe because ptherm hasn't been configured yet and will be a
little further down the initialization path. Ptherm should be safe
regarding to runtime reconfiguration.

v2:
  - do not limit this patch to nv84-a3 and make it nv84+

v3:
  - move the ack to fini()
  - disable IRQs on fini()
  - silently ignore un-requested IRQs

The nv31/nv40 impls are actually fairly nv44-specific, since they assume

NV1A is numerically higher than NV17 but generationally lower. Use the

NV11/17/1F/18 come after NV10/15/16/1A. In order to facilitate using
numerical comparisons, split up the two sets into different card types.

This change should be a no-op except that the relevant cards will see
NV11 printed instead of NV10 for the family.

This fixes a reported locking inversion when interacting with the DRM

This is a necessary step towards being able to work with the insane locking
requirements of the DRM core's vblank routines, and a nice cleanup as a
side-effect.

This is similar in spirit to the interfaces that Peter Hurley arrived at
with his nouveau_event rcu conversion series.

Most nouveau event handlers have storage in 'static' containers
(structures with lifetimes nearly equivalent to the drm_device),
but are dangerously reused via nouveau_event_get/_put. For
example, if nouveau_event_get is called more than once for a
given handler, the event handler list will be corrupted.

- A couple of fixes that never made it into fixes-3.12
- Make NO_EVICT bo's available for shrinkers when on delayed-delete list
- Allow retrying page-faults that need to wait for GPU.

* 'ttm-next-3.13' of git://people.freedesktop.org/~thomash/linux:
  drm/ttm: Fix memory type compatibility check
  drm/ttm: Fix ttm_bo_move_memcpy
  drm/ttm: Handle in-memory region copies
  drm/ttm: Make NO_EVICT bos available to shrinkers pending destruction
  drm/ttm: Allow vm fault retries

Pull request for vmwgfx. Currently just the DMA address stuff.

* 'vmwgfx-next-3.13' of git://people.freedesktop.org/~thomash/linux:
  drm/vmwgfx: Use the linux DMA api to get valid device addresses of pages
  drm/ttm: Enable the dma page pool also for intel IOMMUs

Also check the busy placements before deciding to move a buffer object.
Failing to do this may result in a completely unneccessary move within a
single memory type.
