  perf top: Show backtrace when handling a SIGSEGV on --stdio mode (2015-08-19 15:16:08 -0300)

----------------------------------------------------------------
perf/urgent fixes:

User visible:

- 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)
