Qiaowei Ren ed7b6dbc95 add memory bandwidth meter
Some Intel processor families (e.g. the Intel Xeon processor E5 v3
family) introduced MBM (Memory Bandwidth Monitoring) to measure
bandwidth from one level of the cache hierarchy to the next by
applications running on the platform. It supports both 'local
bandwidth' and 'total bandwidth' monitoring for the socket. Local
bandwidth measures the amount of data sent through the memory
controller on the socket and total b/w measures the total system
bandwidth. This patch introduces two new meters to get memory
bandwidth statistics based on Intel CMT feature.
