function.

This function is normally called once at boot time by the device
driver for the console device, whatever that turns out to be for the
machine. The console procedure is only called to print messages that
are to be printed, the filtering for log level is done already.

Only one console can exist at a time, and there is no way to know if
any other device has registered as a console.
