    During the review of Coffee Lake workarounds Mika pointed out
    that WaDisableKillLogic and GEN9_DISABLE_OCL_OOB_SUPPRESS_LOGIC
    should be removed from CFL and with that I should carry the rv-b.
    
    However when doing the v2 I removed another Workaround that should
    remain because although not mentioned by spec the history of hangs
    around it advocates on its favor.
    
    On some follow-up patches I continued operating on the wrong
    workardound, but Ville noticed that, so here is the fix for the
    current CFL code that is upstream already.
