Cover letter [RFC][PATCH 0/8] perf pmu interface

These patches prepare the perf code for multiple pmus (no user interface yet, Lin Ming is working on that). These patches remove all weak functions and rework the struct pmu interface.

The latter is inspired by the work Frederic is doing to to filter out IRQ contexts.

These patches are very prelimenary, they haven't seen a compiler yet and the last patch still needs sparc,ppc and arm converted.

But they patches seem to be in a good enough shape to see what people think..

comments?
