[PATCH v5 1/2] perf tools: Sync perf_event_attr::config3 addition

From: Rob Herring
Date: Fri Feb 17 2023 - 17:32:47 EST


Arm SPEv1.2 adds another 64-bits of event filtering control. As the
existing perf_event_attr::configN fields are all used up for SPE PMU, an
additional field is needed. Add a new 'config3' field.
