Christian Ehrhardt 0bcdcf28c9 sched: Fix missing sched tunable recalculation on cpu add/remove 
Based on Peter Zijlstras patch suggestion this enables recalculation of
the scheduler tunables in response of a change in the number of cpus. It
also adds a max of eight cpus that are considered in that scaling.
