would remove compat_ptr() conversion from nmask above if I'm not mistaken.
Maybe I'm misremembering how compat syscalls work on s390. 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.
