Doesn't SYSCALL_DEFINEx(sys_mbind) still create two entry points __s390x_sys_mbind() and __s390_sys_mbind() with different argument conversion (__SC_CAST vs __SC_COMPAT_CAST)? I thought that was the whole point of the macros.
You are remembering correctly, probably because you implemented it ;) I totally forgot - sorry for the noise!
