Assuming we don't mix events of different pmus onto a single context (with the exeption of software events inside a hardware group) we can now assume that all events on a particular context belong to the same pmu, hence we can disable the pmu for the entire context operations. This reduces the amount of hardware writes. The exception for swevents comes from the fact that the sw pmu disable is a nop.
