Peter P Waskiewicz Jr cbc82b1726 x86: Add support for Intel Cache QoS Monitoring (CQM) detection ... This patch adds support for the new Cache QoS Monitoring (CQM) feature found in future Intel Xeon processors. It includes the new values to track CQM resources to the cpuinfo_x86 structure, plus the CPUID detection routines for CQM. CQM allows a process, or set of processes, to be tracked by the CPU to determine the cache usage of that task group. Using this data from the CPU, software can be written to extract this data and report cache usage and occupancy for a particular process, or group of processes. More information about Cache QoS Monitoring can be found in the Intel (R) x86 Architecture Software Developer Manual, section 17.14.
