Includes all the core infrastructure to measure the total_bytes and bandwidth. We have per socket counters for both total system wide L3 external bytes and local socket memory-controller bytes. The OS does MSR writes to MSR_IA32_QM_EVTSEL and MSR_IA32_QM_CTR to read the counters and uses the IA32_PQR_ASSOC_MSR to associate the RMID with the task. The tasks have a common RMID for CQM (cache quality of service monitoring) and MBM. Hence most of the scheduling code is reused from CQM.
