When configuring hwpmc to use the EXT_SNOOP event, only send a default cachestate qualifier on the Atom processor. Other Intel processors do not accept a cachestate qualifier and currently hwpmc will return EINVAL if you try to use the EXT_SNOOP event on those processors Approved by: emaste (mentor)

- Support for uncore counting events: one fixed PMC with the uncore domain clock, 8 programmable PMC. - Westmere based CPU (Xeon 5600, Corei7 980X) support. - New man pages with events list for core and uncore. - Updated Corei7 events with Intel 253669-033US December 2009 doc. There is some removed events in the documentation, they have been kept in the code but documented in the man page as obsolete. - Offcore response events can be setup with rsp token.

Not all Intel Core (TM) CPUs implement PMC_CLASS_IAF fixed-function counters. For such CPUs, use an alternate mapping of convenience names to events supported by PMC_CLASS_IAP programmable counters.

Document the fact that some Core2 family CPUs lack fixed-function counters.
