The cpumf_pmu_notfier() hotplug callback lacks handling of the CPU_DOWN_FAILED case. That means, if CPU_DOWN_PREPARE failes, the PMC of the CPU is not setup again. Furthermore the CPU_ONLINE_FROZEN case will never be processed because of masking the switch expression with CPU_TASKS_FROZEN. Add handling for CPU_DOWN_FAILED transition to setup the PMC of the CPU. Remove CPU_ONLINE_FROZEN case. Signed-off-by:
