[PATCH 0/5] perf/arm-cmn: Support CMN S3 r2

Another year, another CMN - although arguably this was last year's
CMN, and is still the same in name as the year before that, but in
implementation the newer releases have significantly updated the HN-S
PMU features, pushing the previous filtering abstraction beyond its
breaking point. As before I've tried to break the refactoring and
functional changes up into reasonably logical chunks so there's some
vague hope of anyone being able to review it...

Cheers,
Robin.
