I was talking about the ABI, so it doesn't actually matter
what the kernel is: any userspace ABI without
CONFIG_COMPAT_32BIT_TIME is equally affected here. On riscv32
this is the only allowed configuration, while on others (arm32
or x86-32 userland) you can turn off COMPAT_32BIT_TIME on
both 32-bit kernel and on 64-bit kernels with compat mode.
