Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
- Fix buildid processing done at the end of a 'perf record' session, a
problem that happened in workloads involving lots of small short-lived
processes. That code was not asking the perf_session layer to order
the events.
Make the code more robust to handle some of the problems with such
out-of-order events and fix 'perf record' to ask for ordered events
on systems where we have perf_event_attr.sample_id_all. (Adrian Hunter)
- Show backtrace when handling a SIGSEGV in 'perf top --stdio' (Arnaldo Carvalho de Melo)
