Subject: [PATCH v7 2/8] perf metric: "Compat" supports matching multiple identifiers
The jevent "Compat" is used for uncore PMU alias or metric definitions.
The same PMU driver has different PMU identifiers due to different
hardware versions and types, but they may have some common PMU metric.
Since a Compat value can only match one identifier, when adding the
same metric to PMUs with different identifiers, each identifier needs
to be defined once, which is not streamlined enough.
So let "Compat" supports matching multiple identifiers for uncore PMU
metric.
