#     cpufreq:powernv: Fix unsafe notifiers
#     
#     The PowerNV cpufreq driver registers two notifiers: one to catch
#     throttle messages from the OCC and one to bump the CPU frequency back
#     to normal before a reboot. Both require the cpufreq driver to be
#     registered in order to function since the notifier callbacks use
#     various cpufreq_*() functions.
#     
#     Right now we register both notifiers before we've initialised the
#     driver. This seems to work, but we should head off any protential
#     problems by registering the notifiers after the driver is initialised.
