When converting the posix-cpu-timers, it call the cputime_to_timespec() function. Thus it need a conversion for this function. You can see that conversion in patch "posix-cpu-timers: Convert to y2038 safe callbacks" from https://git.linaro.org/people/baolin.wang/upstream_0627.git. And I also will explain this in the changelog.
