Vitalii Bursov 4d9d099ab2 sched/fair: Allow disabling sched_balance_newidle with sched_relax_domain_level
[ Upstream commit a1fd0b9d75 ]

Change relax_domain_level checks so that it would be possible
to include or exclude all domains from newidle balancing.

This matches the behavior described in the documentation:

  -1   no request. use system default or follow request of others.
   0   no search.
   1   search siblings (hyperthreads in a core).

"2" enables levels 0 and 1, level_max excludes the last (level_max)
level, and level_max+1 includes all levels.

Fixes: 1d3504fcf5 ("sched, cpuset: customize sched domains, core")
