[RFC PATCH 2/3] sched: change scheduler to give preference to soft affinity CPUs

The soft affinity CPUs present in the cpumask cpus_preferred is used by the scheduler in two levels of search. First is in determining wake affine which choses the LLC domain and secondly while searching for idle CPUs in LLC domain. In the first level it uses cpus_preferred to prune out the search
