The CPUFREQ_NOTIFY and CPUFREQ_ADJUST events of the policy notifiers are removed as a result, but we have to add CPUFREQ_CREATE_POLICY and CPUFREQ_REMOVE_POLICY events to it for the acpi stuff specifically, though they are also used by arch_topology stuff now. So the policy notifiers aren't completely removed. Boot tested on my x86 PC and ARM hikey board. This has already gone through build bot for a few days now.
