[Intel-gfx] [PATCH 12/16] drm/i915: Swap if(enable_execlists) in i915_gem_request_alloc for a vfunc

Wed Dec 7 13:58:29 UTC 2016
A fairly trivial move of a matching pair of routines (for preparing a
request for construction) onto an engine vfunc. The ulterior motive is
to be able to create a mock request implementation.
