I just had another look at the topic and it seems with just need a minimal patch to add SECCOMP and SECCOMP_FILTER support when looking at the changes for riscv64 [1].
The most complex change seem to be the changes in entry.S to add some additional checks for syscall numbers. I think we could just do this for m68k (and SH) as well. The userland land part is trivial as well, I actually added SuperH support to libseccomp today which was rather easy but my pull request was rejected for the time being due to SuperH not supporting SECCOMP_FILTER yet (only basic SECCOMP). So, if someone could do the kernel pieces for m68k, I would work on the userspace changes in libsseccomp.
