Attached patch implements sysctl/procfs scheduler tunables, knobs which
let one play with all of the important scheduler variables:

sched.starvation_limit = 2000
sched.max_sleep_avg = 2000
sched.interactive_delta = 2
sched.prio_bonus_ratio = 25
sched.exit_weight = 3
sched.parent_penalty = 100
sched.child_penalty = 95
sched.min_timeslice = 10
sched.max_timeslice = 300

Also in /proc/sys/sched/

Which may help in tuning and debugging the scheduler.

I believe Ingo did something similar to this ages ago, so original
credit for the idea goes to him.

Note the values are not checked and you can probably cause a
divide-by-zero somewhere, but only root can write these.
