This all happens in the Linux Kernel early during IPL. The translation from "condev" to the actual device number takes place when we parse the kernel command line. To get the device number we just use the information provided by the console driver (and if that information is incorrect we fail to IPL regardless of specifying "condev"). When we scan for ccw devices later during IPL we omit those on the ignore list.
