The worst thing is that gnu patch will make
this decision on a per-file basis, so you
can't then back out the changes with -R.

Do like this:

diff -Naurd old new

IMPORTANT: the directory names should have
the same number of characters in them.
Do not try something like:

diff -Naurd bad idea
diff -Naurd doomed 2fail

Don't use "linux" for a name. Don't use
anything Linus might use. Pick your own
equal-length directory names, and don't
distribute tarballs containing them.
This prevents source-destroying disasters.

Then to apply:

(cd my-linux && bzip2 -dc ../foo.bz2 | patch -p1 -s -E)
