>     drm/i915: Stop parking the signaler around reset
>     
>     We cannot call kthread_park() from softirq context, so let's avoid it
>     entirely during the reset. We wanted to suspend the signaler so that it
>     would not mark a request as complete at the same time as we marked it as
>     being in error. Instead of parking the signaling, stop the engine from
>     advancing so that the GPU doesn't emit the breadcrumb for our chosen
>     "guilty" request.
>     
>     v2: Refactor setting STOP_RING so that we don't have the same code thrice
