I noticed m68knommu has in include/asm-m68knommu/unistd.h:
#define __NR_restart_syscall 0
and in arch/m68knommu/kernel/signal.c:
regs->d0 = __NR_restart_syscall;
while m68k doesn't have __NR_restart_syscall and handles syscall restarts
differently.
Furthermore, both arch/m68knommu/kernel/syscalltable.S and
arch/m68k/kernel/entry.S have for entry 0:
.long sys_ni_syscall /* 0 - old "setup()" system call*/
i.e. on m68knommu system call restarting doesn't do anything.
