[Intel-gfx] Context churn

[Chris Wilson]

The essence of this series is to just rename the anonymous struct inside
intel_context. But since it involves churn, I added some sweetner into
the miex (and more churn)!

[PATCH v2 04/11] drm/i915: Rename i915_gem_context_reference/unreference() 

Long term plan is to migrate all of our reference manipulation over to
the core kref_get/kref_put idiom. Whilst I was changing contexts, adding
the churn here seemed sensible.

Wants somebody to second my crazy plan for consistent naming.

[PATCH v2 06/11] drm/i915: Move pinning of dev_priv->kernel_context

Tvrtko spotted a missed idr_remove on an error path, v2 needs an r-b.

[PATCH v2 07/11] drm/i915: Show i915_gem_context owner in debugfs

Tvrtko spotted that we never mark the file_priv as closed, brought that
earlier in the queue (to this v2).

[PATCH v2 10/11] drm/i915: Rearrange i915_gem_context

Tvrkto has r-b this, I've just managed to forget to add it.

[PATCH v2 11/11] drm/i915: Show context objects in

Any takers?
