----------------------------
-These are notified when a new policy is intended to be set. Each
-CPUFreq policy notifier is called twice for a policy transition:
+These are notified when a new policy is created or removed.
-1.) During CPUFREQ_ADJUST all CPUFreq notifiers may change the limit if
- they see a need for this - may it be thermal considerations or
- hardware limitations.
-
-2.) And during CPUFREQ_NOTIFY all notifiers are informed of the new policy
- - if two hardware drivers failed to agree on a new policy before this

The third argument, a void *pointer, points to a struct cpufreq_policy
