I have some patches ready for release after the merge window. I
noticed conflicts between my development tree on top of
tip/perf/x86-ibs and tip/perf/core. Could you merge tip/perf/core into
tip/perf/x86-ibs? I will rebase my current patches then. This avoids
diverging the trees to much and reduces later conflicts.

Thanks,
