Subject: [PATCH v3 3/3] perf vendor events: Remove bad jaketown uncore events
The event converter scripts at:
https://github.com/intel/event-converter-for-linux-perf
passes Filter values from data on 01.org that is bogus in a perf command
line and can cause perf to infinitely recurse in parse events. Remove
such events or filters using the updated patch:
https://github.com/intel/event-converter-for-linux-perf/pull/15/commits/afd779df99ee41aac646eae1ae5ae651cda3394d
Fixes: 376d8b581b76 ("perf vendor events: Update Intel jaketown")
Signed-off-by: Ian Rogers <irogers@...gle.com>
