Subject: [PATCH 3/3] perf tools: Get rid of unused 'swapped' parameter from perf_event__synthesize_sample()
There is never a need to synthesize a 'swapped' sample, so all callers to
perf_event__synthesize_sample() pass 'false' as the value to 'swapped'. So
get rid of the unused 'swapped' parameter.
