Linux-2.6.12-rc2 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!

ppp: Change copyright notices from ANU to me This changes the copyright notices on the PPP code that I developed in the late 1990s from being copyright The Australian National University to copyright Paul Mackerras. I can do this as I have an acknowledgement in writing from the Head of the Computer Science Department at ANU (where I worked then) that ANU does not claim any intellectual property in this code. While I'm at it, change the copyright notice from BSD-style to GNU GPL like the rest of the kernel. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: David S.
