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.
