Kan Liang 33636732dc perf/x86/intel: Fix bug for "cycles:p" and "cycles:pp" on SLM ... cycles:p and cycles:pp do not work on SLM since commit: 86a04461a9 ("perf/x86: Revamp PEBS event selection") UOPS_RETIRED.ALL is not a PEBS capable event, so it should not be used to count cycle number. Actually SLM calls intel_pebs_aliases_core2() which uses INST_RETIRED.ANY_P to count the number of cycles. It's a PEBS capable event. But inv and cmask must be set to count cycles. Considering SLM allows all events as PEBS with no flags, only INST_RETIRED.ANY_P, inv=1, cmask=16 needs to handled specially.
