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
