The hotplug notifier rcutorture_cpu_notify() doesn't consider the corresponding CPU_XXX_FROZEN transitions. They occure on suspend/resume and are usually handled the same way as the corresponding non frozen transitions.
Mask the switch case action argument with '~CPU_TASKS_FROZEN' to map CPU_XXX_FROZEN hotplug transitions on corresponding non frozen transitions.
