I am seeing a build failure with perf:

tools/perf/util/evlist.c: In function evlist__add_aux_dummy:
tools/perf/util/evlist.c:266:31: error: implicit declaration of function
evlist__dummy_event; did you mean evlist__add_sb_event’?
[-Werror=implicit-function-declaration]
266 | struct evsel *evsel = evlist__dummy_event(evlist);
| ^~~~~~~~~~~~~~~~~~~
| evlist__add_sb_event

I think we should drop these three commits:

20a5799cae7dc perf evlist: Avoid frequency mode for the dummy event
7de783c81c7e7 perf tools: Get rid of evlist__add_on_all_cpus()
141ce9207068e perf evlist: Add evlist__add_dummy_on_all_cpus()

Backport was requested here:
https://lore.kernel.org/stable/CAL715WLTjMGQrhm6wWqFSeL_Oq-HzoQd5CqewvLRLv0Xbnibgw@mail.gmail.com/

Thanks,
