[PATCH 08/15] drm/i915: Move execlists defines from .c to .h

Dave Gordon
2015-06-15T18:38:19Z

From: "Michael H. Nguyen" <michael.h.nguyen@intel.com>

Move defines from intel_lrc.c to i915_reg.h so they are accessible
to the GuC submission code; and expose a previously static function
in the execlist code which will also be required for GuC submission.

Issue: VIZ-4884
