To be clear, I have not done any work with ILP32 nor do I have any
immediate plans to do so (other tasks are higher priority).  I am not
sure what details you are looking for, but there are several
arches/ABIs in the kernel, including regular aarch64, that can serve
as examples on how to enable syscall auditing (presumably that is what
you are interested in with this thread).  There may be some
interesting challenges with ILP32 due to overlap with aarch64
syscalls, but I haven't looked closely enough at ILP32 to say that
with any certainty.
