Peter Zijlstra c9bc1753b3 perf: Fix __perf_event_overflow() vs perf_remove_from_context() race ... Make sure that __perf_event_overflow() runs with IRQs disabled for all possible callchains. Specifically the software events can end up running it with only preemption disabled. This opens up a race vs perf_event_exit_event() and friends that will go and free various things the overflow path expects to be present, like the BPF program.
