  perf tools: Fix fault in error patch of intel_pt_process_auxtrace_info() (2016-02-01 12:03:35 -0300)

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

- tracepoint_error() can receive e=NULL, robustify it, fixes a problem noticed
  with a very specific combination: Machine with Intel PT (e.g. Broadwell),
  kernel with no perf_event_attr.context_switch feature (e.g. 4.2) and unreadable
  tracefs (for instance !root users), making the fallback from
  perf_event_attr.context_switch to the sched:sched_switch tracepoint to fail
  reading its info from tracefs, fix it. (Adrian Hunter)

- Fix fault in error path of intel_pt_process_auxtrace_info(), obeying
  the existing 'struct thread' lifetime cycle checking expectations, noticed
  for instance, when processing perf.data files with Intel PT data using
  'perf script' (Wang Nan)
