Ok, but if the whole series is needed, isn't it better if it all goes into 3.17? Otherwise 3.17 is a clear regression for some users; it's definitely for me since before 3.17-rc1 I never saw this bug and now I see it every time I do something CPU intensive. Maybe the regression is acceptable because the it's confined to some CONFIG_NO_HZ_* combination (I think) which is still rather experimental, that's your call to make, but it's still a regression.
