Performance for the two patches:
First patch:  100 fps
second patch: 105 fps (LLC default )
Both patches: 105 fps 

But I don't know how to try both patches:
eLLC default 
     if (level != I915_CACHE_NONE)
-        pte |= HSW_WB_ELLC_LLC_AGE0;
+        pte |= HSW_ELLC;

LLC default 
      if (level != I915_CACHE_NONE)
-        pte |= HSW_WB_LLC_AGE0;
+        pte |= HSW_LLC;

Does it mean:
if (level != I915_CACHE_NONE)
-        pte |= HSW_WB_ELLC_LLC_AGE0;
+        pte |= HSW_ELLC;
+               pte |= HSW_LLC;</pre>
