[PATCH 4/4] perf intel-pt, intel-bts: Suppress useless AUX records by default

From: Alexander Shishkin
Date: Thu Nov 09 2017 - 12:25:53 EST


This makes use of the shiny new attr::suppress_aux that suppresses the
AUX records that don't carry any 'interesting' information for the
decoders, that is PERF_RECORD_AUX[flag==OVERWRITE], which just stack up
in the DATA buffer for no good reason.
