The other large missing piece is the system call implementation. I have

I assume that this also means there hasn't been much thought about
userspace support above libc?  i.e., how to take a 64-bit time64_t (or
changing the size of time_t) and translating that to a string using
some kind of version of ctime() and asctime(), and how to parse a
post-2038 date string and turning it into a 64-bit time_t on a 32-bit
platform?


Arnd, I would just like to tell you how much I welcome your decision for a new __kernel_time64_t! As a time[64]_t is basically well defined counting artificial seconds since the epoch (1970-01-01 00:00) where every year divisible by four is a leap year that is for the meanwhile already sufficient to make use of your new type. I just think about the Mayan calendar application which I have implemented last year (Though I have not brought it to a publishable state yet). A single typedef should be sufficient to let it make use of time64_t (it directly uses this type as well as long long internally for its calculations rather than the glibc time format functions).
