[RFC 0/3] perf stat: improvements for handling of multiple PMUs

[Agustin Vega-Frias]

This series of patches adds some simple improvements to the way perf stat
handles PMUs that have multiple instances by:

1. Adding glob-like matching in addition to the prefix-based matching
   introduced previously (patch 1).
2. Adding the ability to recover the PMU names when printing the events
   separately with the --no-merge option (patch 2).
3. Restoring auto-merge for events created by prefix or glob-like match
   (patch 3). Note that this still keeps the behavior that disables
   auto-merging of legacy symbolic events (e.g. cycles).

Agustin Vega-Frias (3):
  perf, tools: Support wildcards on pmu name in dynamic pmu events
  perf, tools: Display pmu name when printing unmerged events in stat
  perf pmu: Restore auto-merging of PMU events created by prefix match
