The FROZEN transitions are used when a CPU suspends/resumes. In case of a suspend/resume, only the up prepare (CPU_UP_PREPARE_FROZEN) is handled. The error handling transition CPU_UP_CANCELED_FROZEN as well as the CPU_ONLINE_FROZEN transition are not handled. Masking the switch case action argument with ~CPU_TASKS_FROZEN, to handle all FROZEN tasks the same way than the corresponding non frozen tasks.
