Cover letter [patch 00/21] perfmon2 minimal: introduction

Hello,

The following patches implement a minimal perfmon2 subsystem which provides access to the hardware performance counters of modern processors.

This series supports ONLY per-thread counting of PMU events (no sampling) for AMD64 and Intel processors supporting architectural perfmon (version 1 and 2) in both 32 and 64 bit modes.

Please review.
