Hm, it's even messier.  With your patch, we get:
	*** Warning: "__send_sig_info" [drivers/usb/core/usbcore.ko] undefined!
	*** Warning: "__put_task_struct" [drivers/usb/core/usbcore.ko] undefined!
when the USB core is a module.

I can't pass judgement if we want to export both of these functions to
modules...  Anyone else know?

thanks,
