Ok, I'll use a cover letter in future ones like so.

The above had already been merged into upstream, at least I can see them
in tip/master now.

Patch series below is about replacing deprecated 
rtc_tm_to_time()/rtc_time_to_tm()
mostly in rtc drivers with their y2038-safe substitutes 
rtc_tm_to_time64()/
rtc_time64_to_tm() which were merged into upstream last year.

And in the following one, I want to replace all the xxx_persistent_clock()
architecture implementations with xxx_persistent_clock64() or simply 
remove
it if can(mainly for rtc-related persistent clock).

I think you can only review the two v2 series :-)
