[Chris Wilson]

Quoting Michał Winiarski (2017-10-25 21:00:18)
> We would also like to make use of execlist_cancel_port_requests and
> unwind_incomplete_requests in GuC preemption backend.
> Let's rename the functions to use the correct prefixes, so that we can
> simply add the declarations in the following patch.
> Similar thing for applies for can_preempt, except we're introducing
> HAS_LOGICAL_RING_PREEMPTION macro instad, converting other users that
> were previously touching device info directly.
> 
> v2: s/intel_engine/execlists and pass execlists to unwind (Chris)
> v3: use locked version for exporting, drop const qual (Chris)
