Chris Wilson c5efa1ad09 drm/i915: Convert engine->write_tail to operate on a request ... If we rewrite the I915_WRITE_TAIL specialisation for the legacy ringbuffer as submitting the request onto the ringbuffer, we can unify the vfunc with both execlists and GuC in the next patch. v2: Drop the modulus from the I915_WRITE_TAIL as it is currently being applied in intel_ring_advance() after every command packet, and add a comment explaining why we need the modulus at all.
