Ingo Molnar 19978ca610 sched: reintroduce SMP tunings again ...

Yanmin Zhang reported an aim7 regression and bisected it down to:

 |  commit 38ad464d41
 |  Author: Ingo Molnar <mingo@elte.hu>
 |  Date:   Mon Oct 15 17:00:02 2007 +0200
 |
 |     sched: uniform tunings
 |
 |     use the same defaults on both UP and SMP.

fix this by reintroducing similar SMP tunings again. This resolves
the regression.

(also update the comments to match the ilog2(nr_cpus) tuning effect)
