s390 defines current_stack_pointer as function while all other
architectures use 'register unsigned long asm("<stackptr reg>").
This make codes like the following from check_stack_object() fail:
if (IS_ENABLED(CONFIG_STACK_GROWSUP)) {
if ((void *)current_stack_pointer < obj + len)
return BAD_STACK;
} else {
if (obj < (void *)current_stack_pointer)
return BAD_STACK;
}
because this would compare the address of current_stack_pointer() and
not the stackpointer value.
