The kbuild bot pointed out that the way I sent this series, the use of
__kernel_old_timespec
causes a build failure, because I introduce this in a separate submission. I'm
moving this patch over to the other series, and changing the subject to

y2038: socket: use __kernel_old_timespec instead of timespec

With the expectation of merging it along with the other core patches.
