I don't think anyone so far had a strong preference here, so I went 
with what Mathieu suggested and kept the original Mac behavior, but 
added the WARN_ON().

So, is this safe to apply?
Especially in light of the warnings seen by Meelis with the PPC version.

You mean, "can we apply this and avoid warning splats?"

Meelis's result says, "no".

I forget what date the RTC gets set to when the PMU/Cuda is reset but I 
suspect that timezone arithmetic in either MacOS or Linux could cause it 
to end up in 1969.

So I'd prefer to see the WARN_ON() removed.
