Ok.
I tried this on current mainline (commit 13d261932) which now includes both of Stephane's patches and repeated the nooploop test.
The problem still exists - the number of events reported on Power is far fewer than without the patches.
Aggregated stats: TOTAL events: 78 MMAP events: 47 COMM events: 2 EXIT events: 2 SAMPLE events: 27 cycles stats: TOTAL events: 21 MMAP events: 4 COMM events: 1 EXIT events: 2 SAMPLE events: 14 cycles stats: TOTAL events: 13 SAMPLE events: 13
