Implements verification of - Bits of ESCR EventMask field (meaningful bits in field are hardware predefined and others bits should be set to zero) - INSTR_COMPLETED event (it is available on predefined cpu model only) - Thread shared events (they should be guarded by "perf_event_paranoid" sysctl due to security reason). The side effect of this action is that PERF_COUNT_HW_BUS_CYCLES become a "paranoid" general event.
