which do not support 32-bit time representations. As a consequence glibc
obviously cannot define SYS_futex either.

Mostly.

If Cynthia authored the patch, then this still lacks a 'From: Cynthia...'
at the top of the change log so she can be identified as the
author. Otherwise tooling will attribute autorship to you.
