It's usually risk vs reward on a per patch basis and I don't think of it as a general rule. We've always avoided the CPU tuning backport rule to the FSF branches. The smaller the CPU tuning patch - the better it is and in this case I'm comfortable with the patch going in as it is adding another tuning option, using existing constructs and is not invasive in the backend. Ok for the ARM port if no regressions and there are no objections from the RMs. regards Ramana
