+Subject: [PATCH 5448/5725] drm/amdgpu: Deactivate SW interrupt fallback in
+ amdgpu_fence_process v2
+
+Deactivate SW interrupt fallback when all emited fences are completed.
+Also switch interrupt SW fallback message from INFO to WARN.
+
+v2: shorten the warnign message a bit and only re-activate the timer during
+processing if it was already activated before.
