I know the feeling.

Once that's working, we can convert individual PPC platforms over,
removing the routines from the ppc_md and creating a generic RTC driver
instead. PA Electra is already like that -- because it wasn't a
regression there to have broken NTP sync. But the others need to wait.

Eventually, we ought to be able to drop the RTC functions from the
ppc_md -- and presumably the equivalent for other architectures too.
