struct elf_prstatus and Y2038 (was: Re: [PATCH v4 06/13] C-SKY: Linux ABI)

Speaking of this file, I think we still need a solution for elf_prstatus
containing a 'timeval' after time_t becomes 64-bit wide. I actually
have a patch to change the kernel header file declaring the
same structure, but I had not realized that glibc contains another
copy.  mentions
that type, but not what to do about it. What I did in the kernel
was to change the type of pr_utime/pr_stime/pr_cutime/pr_cstime
to something that keeps using 'long' fields. Given that we can't
change the file format in an incompatible way, and that 32-bit
is sufficient here, that seemed like the most appropriate solution.

Keeping 32 bits there looks reasonable. I thought we had a port where time_t isn't long, but that doesn't seem to be the case.

Ah, I think it's actually s390, where suseconds_t is int, not long.

Presumably that will need a special case so that existing format specifiers etc. are not disturbed unnecessarily.
