Merge branches 'timers-urgent-for-linus' and 'perf-urgent-for-linus' of git://

Pull timers and perf fixes from Ingo Molnar:
 - Fix another timekeeping bug

   - 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

  There's this infrastructure change:

   - Prep work for the DWARF CFI post unwinder, so that it doesn't use
     perf_session in lots of places, just evlist/evsel is enough.

  which is a late infrastructure change that prepare for future feature
  work - we wanted it upstream to simplify the fixes/development patch
