!3372 Cluster scheduler support

Merge Pull Request from: @aubrey-intel 
 
The cluster scheduler support in this context is about enhancing the Linux kernel's scheduler for systems where sets of CPU cores share an L2 cache or other mid-level caches/resources.

On x86_64 side a testing with Intel's Jacobsville platform showed up to a 25% improvement with the load being better balanced between L2 clusters. Also, not all workloads will benefit from this cluster scheduler work.

On the ARM side there were Stream memory benchmark improvements up to 19%, PBZIP2 performance by up to 8%, PIXZ performance up to a few percent, and also a number of SPECrate wins, but not a universal win either.
