Given the conditional you are putting this under: should I take it it is
specifically for 32-bit kernels and the system calls *are* available for
32-bit binaries executed under 64-bit kernels?

Yes, the intention is specifically for 32-bit kernels. This patch makesinterfacing older 32-bit kernels work.

The system calls are available in 64-bit kernels since before Linux 3.2.I don't have the possibility to test the case with 32-bit binaries undera 64-bit kernel, so I don't want to touch the behavior for that case.


Best regards,
