17f41571bb2c4a is only in perf/core, x86/jumplabel is missing it. I am not 
sure about the tip workflow, but as it is now, x86/jumplabel is buggy, so 
it should be either fixed (by pulling 17f41571bb2c4a from perf/core) or 
removed, or somehow marked as broken ... ?

Not a big deal for me as long as perf/core is fine, but as you were 
mentioning it ...

Thanks,
