Tim Chen def4ef5550 scheduler: Add runtime knob sysctl_sched_cluster
commit 8ce3e706b31409147f035c037055caa68e450ce5 openeuler.
Reference: https://lore.kernel.org/lkml/cover.1638563225.git.tim.c.chen@linux.intel.com/

----------------------------------------------------------------------

Allow run time configuration of the scheduler to use cluster
scheduling.  Configuration can be changed via the sysctl variable
/proc/sys/kernel/sched_cluster. Setting it to 1 enable cluster
scheduling and setting it to 0 turns it off.

Cluster scheduling should benefit independent tasks by load balancing
them between clusters.  It reaps the most benefit when the system's CPUs
are not fully busy, so we can spread the tasks out between the clusters to
reduce contention on cluster resource (e.g. L2 cache).

However, if the system is expected to operate close to full utilization,
the system admin could turn this feature off so as not to incur
extra load balancing overhead between the cluster domains.
