Subject: [PATCH 0/3] fix rescaling of scheduler tunabled

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.

The series has not yet got the testing it shouldhave, just some basic
functionality tests. But working day is ending and the patches are fine
enough for another round of discussion about the basic ideas and
implementation.

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
