Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core fixes and some late updates from Arnaldo Carvalho de Melo:
* Make clean brace expansion fix for some shells, from Palmer Cox
* Warn user just once per guest kernel when not finding kernel info,
from David Ahern
* perf test fix from Jiri Olsa
* Fix error handling on event creation in perf top, from David Ahern
* Fix check on perf_target__strnerror, from Namhyung Kim
* Save the whole cmdline, from David Ahern
* Prep work for the DWARF CFI post unwinder, so that it doesn't
uses perf_session in lots of places, just evlist/evsel is enough.
