Ok, thanks for clarifying.

Agreed, we should split that out on all architectures as well.
Almost the same set of architectures that have sys_socketcall also
have sys_ipc, and the reasons for changing are identical. I don't
think we have any other system calls that are handled like this
on some architectures but not on others. There are a couple of
system calls (e.g. futex) that are also multiplexers, but at
least they do it consistently.
