We currently have sysctl, procfs and debugfs SCHED_DEBUG interfaces, end the insanity and move (most) everything to debugfs.
And since this is a nice moment to have people re-evaluate their 'tunings' also change how some of the values work. v2: - picked up tags - latestest version of that debugfs_create_str() thing (no extra \0, no export, no write) (rasmus) - re-added missing __cpumask_clear_cpu() (valsch) - use min() for BASE_SLICE (vingu)
