drm: Fix dma fence stub fix so the lock is actually initialized.

Tested but forgot to amend change before exporting to CVS again.

drm: Fix dma fence stub so it works with locking operations.

drm: Convert membar_enter/exit stragglers to membar_acquire/release.

drm: Use atomic_load_consume/relaxed to simplify code.

drm: Support 64-bit fence context and sequence numbers.

drm: Make sure dma_fence_wait gets traced too. Deduplicate.

drm: Add dtrace probes to fences.

drm: Fix signalling return value if no enable_signaling op.

drm: Use atomic_load_relaxed for fence->flags when not locked.

Shouldn't make a semantic difference on any machines we run on, but
will make sanitizers happier and emphasize to readers that the resu

drm: Use atomic_load_relaxed for fence->flags when not locked.

Shouldn't make a semantic difference on any machines we run on, but
will make sanitizers happier and emphasize to readers that the result
may not be reliable at these points.

drm: Assert dma_fence_wait internal return value.

drm: Rework timeout return code logic.

drm: Rework dma_fence_wait_any_timeout.

- Yield the first index, not the most recently signalled one.
- Check again after last wakeup.
- Make sure to return positive for nontimeout.
- Handle ip=null.

drm: Set fence->ops for stub fences too.

drm: set f_magic in the stub fence.

drm: In dma_fence_wait_timeout, allow MAX_SCHEDULE_TIMEOUT.

In the Linux API, this means wait forever.

drm: Print bad timeout in dma_fence_wait_timeout kasserts.

drm: dma_fence_get allows fence to be null; fix assertion.

While here, update comments about semantics for dma_fence_get and
dma_fence_get_rcu (which does not allow null fence).

drm: Set fence timestamps -- i915 uses them.

drm: Sprinkle assertions about fence lifetime.

drm: Add a kassert for fence destruction.

drm: Skip enabling signalling for fence if already signalled.

drm: Ensure the fence callback is initialized on failure.

drm: Rework enable-signal logic to match Linux.
