Hmm, patches 1..4,6 are in linux-tip and Arnaldo's trees but patch 5 is
in neither.

| No. The event format is different on most POWER cpus, in particular it
| is different on Power6 and Power7, and will be different again on
| Power8.
Sigh. The port of this patchset to Power6 has not started yet.
But this patchset does work on Power7 correct ?
If so, and we figure out what happened to patch 5, can we add a patch to
to move the format code to power7-pmu.c ?
