The tty driver write method is different to the usual fops device write
methods as the buffer is already in kernel space. Clarify the docs since
someone writing a driver made that mistake.

While trying to develop a line discipline I found a couple of things worth
mentioning in Documentation/tty.txt which weren't, so I decided to add
them.  It would be nice if someone more knowledgeable than me in that area
would look over them, in case I got something wrong.

It's a bit strange to see tty_register_ldisc call in modules' exit

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
