-- Switch to working in original kernel git repo to track
changes of original kernel source more convieniently
in the working directory --

When you want to switch to original kernel git repo, do this:

<clone original kernel repo>
cd ~/yadro-git/
git checkout v2.6.19
git checkout -b my_test_branch
git rm .gitignore
git commit -m 'rm .gitignore'
rm -fr * # leave only .git/
cp -r ~/kernel-git/* .
git add .
git add -u .
git commit -m 'a bunch of changes'
<copy/paste git customization commands from 0000-git/README>
<do whatever you want>

When you want to save modifications that you made in your
original-kernel-source-working-directory to kernel-git to save
them to github, do this:

cd ~/kernel-git/
git pull
rm -fr * # leave only .git/
cp -r ~/yadro-git/* .
git add .
git add -u .
git commit -m 'a bunch of changes'
