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.
