This is a perfect example why doing this piecewise is the only way to
go! And even that is not easy:

I don't have this line in util/pmu.c:788 so I can't trigger it:

   782  bool pmu_have_event(const char *pname, const char *name)
   783  {
   784          struct perf_pmu *pmu;
   785          struct perf_pmu_alias *alias;
   786  
   787          pmu = NULL;
   788          while ((pmu = perf_pmu__scan(pmu)) != NULL) {
   789                  if (strcmp(pname, pmu->name))
   790                          continue;
   791                  list_for_each_entry(alias, &pmu->aliases, list)
   792                          if (!strcmp(alias->name, name))
   793                                  return true;
   794          }
   795          return false;
   796  }

So, I've done the patch ontop of those branches:

    perf symbols: Get kernel start address by symbol name

by checking out acme/perf/core first.

So, guys, can we agree on a common branch to apply patches ontop please?

Thanks a lot.
