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.
