Peter Zijlstra 2a5bf23d5b perf/x86/intel: Fix regression by default disabling perfmon v4 interrupt handling ... Kyle Huey reported that 'rr', a replay debugger, broke due to the following commit: af3bdb991a ("perf/x86/intel: Add a separate Arch Perfmon v4 PMI handler") Rework the 'disable_counter_freezing' __setup() parameter such that we can explicitly enable/disable it and switch to default disabled. To this purpose, rename the parameter to "perf_v4_pmi=" which is a much better description and allows requiring a bool argument.
