Perhaps I got a little too aggressive with that patch. The warnings look
to be caused by:

@@ -702,9 +697,7 @@ int __init_or_module do_one_initcall(initcall_t fn)
                strlcat(msgbuf, "disabled interrupts ", sizeof(msgbuf));
                local_irq_enable();
        }
-       if (msgbuf[0]) {
-               printk("initcall %pF returned with %s\n", fn, msgbuf);
-       }
+       WARN(msgbuf[0], "initcall %pF returned with %s\n", fn, msgbuf);
 
        return ret;
 }

I'll just revert that part of the patch, and send that in.

Thanks,
