sched/isolation: Handle the nohz_full= parameter
We want to centralize the isolation management, done by the housekeeping
subsystem. Therefore we need to handle the nohz_full= parameter from
there.
Since nohz_full= so far has involved unbound timers, watchdog, RCU
and tilegx NAPI isolation, we keep that default behaviour.
nohz_full= will be deprecated in the future. We want to control
the isolation features from the isolcpus= parameter.
