Yes, the intention is specifically for 32-bit kernels. This patch makes
interfacing 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 under
a 64-bit kernel, so I don't want to touch the behavior for that case.
Best regards,
