+ * accepts.  Syscalls that receive a pointer to the saved registers are
+ * marked as having zero arguments.
+ *
+ * The binary compatibility calls are in a separate list.
+ *
+ * Entry '0' used to be system_call.  It's removed to disable indirect
+ * system calls for now so user tasks can't recurse.  See mips'
+ * sys_syscall for a comparable example.
