Looks good to me, +/- a couple of things:

 - We _REALLY_ want the freezer to be optional and not enabled by
default on PowerPC. Maybe make it a compile option ?

 - Don't remove the pmu_polled_request() debug code. It's very useful
for debugging and I don't want to have to re-invent it.

Plus I also need to test it on some exotic hardware :-)

Cheers,
Ben.
