I have no idea why faulty commit +1 is reported, but I guess someone
will figure that out....I thought it was the USB one that had bad
influence.
For the range

I didn't do make clean every time, but I hope that had no side effects.
Any other bisects were performed with previous clean.
3a50863f6706ece7719a68be0ae57957164a0f0c is the first bad commit

sched: Fix nohz load accounting
BugLink: http://bugs.launchpad.net/bugs/838811
Various people reported nohz load tracking still being wrecked, but Doug
spotted the actual problem. We fold the nohz remainder in too soon,
causing us to loose samples and under-account.
So instead of playing catch-up up-front, always do a single load-fold
with whatever state we encounter and only then fold the nohz remainder
and play catch-up.
