This patchset is an alternate solution to the original: "[RFC PATCH]
perf cs-etm: Handle valid-but-zero timestamps". It uses the existing
Z option to --itrace instead of modifying the behaviour of the
cs_etm__etmq_get_timestamp() function.

Using timeless mode is equivalent to ignoring 0 timestamps, as
suggested by Mike and Leo.

It applies on top of "[PATCH v3 0/2] perf cs-etm: Set time on
synthesised samples to preserve ordering"

James Clark (3):
  perf cs-etm: Move synth_opts initialisation
  perf cs-etm: Start reading 'Z' --itrace option
  perf cs-etm: Prevent and warn on underflows during timestamp
    calculation.
