Hi Paul.

Originally, I thought, this series also takes care of
the leaf-cfs-runqueue ordering issue described here:
http://lkml.org/lkml/2011/7/18/86
Now, that I had a closer look, I see that it does not take
care of it.
Is there still any reason why the leaf_cfs_rq-list must be sorted?
Or could we just get rid of the ordering requirement, now?
(That seems easier than to fix the issue, as I suspect that
__update_blocked_averages_cpu() might still punch some holes
in the hierarchy in some edge cases.)
I'd like to see that issue resolved. :)
Regards
Jan
