This patch adds the generic Intel uncore PMU support, including helper functions that add/delete uncore events, a hrtimer that periodically polls the counters to avoid overflow and code that places all events for a particular socket onto a single cpu. The code design is based on the structure of Sandy Bridge-EP's uncore subsystem, which consists of a variety of components, each component contains one or more "boxes". (Tooling support follows in the next patches.)
