well, I spent 2 days bisecting between 3.1 and 3.2 (after wasting time bisecting between 3.0 and 3.1 by mistake) (also, a pox on whoever introduced that ethernet .config change between 3.1. 3.2).
and of course what it gives me is a240f76165e6255384d4bdb8139895fac7988799
perf, core: Introduce attrs to count in either host or guest mode
so the test case wasn't crashing because the auto-generated file was setting exclude_guest and exclude_host causing perf_event_open() to fail. If I drop setting those bits it still crashes.
I guess back to the drawing board.
