Because of the PMU's design, many register accesses have side effects which are inter-related, meaning that the normal method of saving CP registers can result in inconsistent state. These side-effects are largely handled in pmu_op_start/finish functions which can be called before and after the state is saved/restored. By doing this and adding raw read/write functions for the affected registers, we avoid migration-related inconsistencies.
