Here's a unified kernel git repo covering 0.0.1 to the present.

[Rob Landley <rob@landley.net>]

Ever done a "git annotate" that stops at 2.6.12-rc2, and wanted to see 
the full history?  Here's an repository that goes all the way back to
0.0.1 (through bitkeeper and all those old tarballs), which otherwise
works as normal (git pull updates it from Linus's tree, you can commit
to it and branch from it, etc)

Here's the tarball:

  http://www.kernel.org/pub/linux/kernel/people/landley/linux-fullhist.tar.bz2

To install it:

  1) Download, extract, cd into the directory.
  2) git checkout -f
  3) git pull

Then use as normal.

This is based on the work of http://padator.org/linux.php with some
trivial cleanups.
