Sebastian Andrzej Siewior 37b502f121 arm/perf: Fix hotplug state machine conversion ... Mark Rutland pointed out that this commit is incomplete: 7d88eb695a ("arm/perf: Convert to hotplug state machine") The problem is that: > We may have multiple PMUs (e.g. two in big.LITTLE systems), and > __oprofile_cpu_pmu only contains one of these. So this conversion is not > correct. > > We were relying on the notifier list implicitly containing a list of > those PMUs. It seems like we need an explicit list here. > > We keep __oprofile_cpu_pmu around for legacy 32-bit users of OProfile > (on non-hetereogeneous systems), and that's all that the variable should > be used for. Introduce arm_pmu_list to correctly handle multiple PMUs in the system.
