Comment 31 for bug 838811

I heard back from Peter Zijlstra who is one of the sched.c mainatiners at kernel.org.
Attached is his signed off patch. There was a one line change since that e-mail, that I will not botther to post here.
I tested what I refer to as the "peter02" patch, and it gives the same results as my proposed patch.
My proposed patch did not deal the very very long idle case for some computers, Peter's does. My computers never take this path, and that this path also needed to be tested is included as a comment in my version 1 proposed patch, see post number 23.

I will post a couple of comparative test result graphs.
