[PATCH 0/3] fix rescaling of scheduler tunables v2

[ehrhardt@linux.vnet.ibm.com]

*updates in v2*
Some testing later v2 has a fix and a few minor changes
- changes of the scaling type update the normalized values according
  to the new factor
- minor fixes to satisfy checkpatch.pl
-> ready for discussion and/or acceptance now :-) 

This patch series is based on the ideas of Peter Zijlstra and me in the
discussion how to fix missing updates to the scheduler tunables in case
of cpu hot add/remove. The values are scaled on boot time but not (yet)
in the runtime #cpu changes.

Series contains:
[PATCH 1/3] sched: fix missing sched tunable recalculation on cpu add/remove
[PATCH 2/3] sched: make tunable scaling style configurable
[PATCH 3/3] sched: update normalized values on user updates via proc v2
