[PATCH 11/11] drm/i915: Move i915_gem_init_contexts() earlier

[Chris Wilson <chris@xxxxxxxxxxxxxxxxxx>]

As the GEM global context setup is now independent of the GT state
(although GT does currently still depending upon the global
i915->kernel_context), we can move its init earlier, leaving the gt init
ready to extracted.
