IOW, if you boot with console=ttyS0 console=tty0 then all kernels prior to this commit will produce output on both ttyS0 and tty0 but input will only be taken from tty0. With this patch the serial console will always be the primary console instead of tty0, potentially preventing people from getting into their machines in emergency situations.
