I guess the performance of that benchmark depends on it
"slipping under the wire" after each time the kernel
zeroes out ->wakee_flips.
Depending on repeatedly pulling the wakee back to the same
node as the waker suggests something else in the kernel may
be pulling the wakee to another place in the system repeatedly,
as well, just at a lower frequency (load balancer?).
I have also noticed that select_idle_sibling often fails to
find an idle sibling within the LLC domain, even when it
exists. Fixing that bug sometimes results in lower performance.
It appears that some of the performance results of the scheduler
appear on the code acting in an opposite way to its documented
intention.
It may be best to revert 096aa33863a for now...
