Apologies for the delay. I've just given these a review.

I note an awful lot of duplication over patches 2-5. The pmu::add
implementations are practically identical, and I suspect can be shared
without much difficulty. Please try to address that unnecessary
duplication.

My comments on patches 2 and 3 larely apply to 4 and 5, so I haven't
reviewed those individually.

Thanks,
Mark.
