Subject: [PATCH v4 3/3] perf: Add support for perf_event_attr::config3
perf_event_attr has gained a new field, config3, so add support for it
extending the existing configN support.
Signed-off-by: Rob Herring <robh@...nel.org>
---
This patch is dependent on the kernel side landing first.
v4:
- Add config3 to event parsing tests
