Subject: [PATCH 0/2] perf/ibs: Fix interface via core pmu events

IBS used to allow event creation via core pmu events with precise_ip
attribute set, but it's broken since late 2019. 1st patch fixes the
issue and 2nd patch adds simple perf test for the same.

  perf/ibs: Fix interface via core pmu events
  perf test: Add selftest to test IBS invocation via core pmu events
