Subject: [PATCH 0 of 2] implement tty driver for netconsole

I have a Kuro Box (a small NAS device running Linux), and it has no serial
console (nor any other console for that matter). The most convenient way to get
boot output is via the netconsole driver, which is what most Kuro owners do. (The u-boot
firmware even supports interactive netconsole allowing us to edit boot configuration.)

However, once past kernel boot, userspace currently has no way of outputting data over
netconsole. These patches enable that, which is really useful for seeing init
script output and debugging ramdisks before they've brought up sshd.
