Unfortunately this is not the definition we want on big-endian systems because it puts the tv_nsec field in the wrong place.

Indeed!

You can either uses the simple (non-POSIX) __kernel_timespec definition in nolibc with a 64-bit tv_nsec, or copy the more complicated definition with explicit padding that is used in musl and glibc.

I think that switching this patch and the next one (10/12) would just do the trick since both fields will become __kernel_time64_t. Or maybe the two should be squashed into a single one.
