In the my-wireless-testing directory:
git pull git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
or:
git pull ../linux-2.6.git (which gets it from the other clone you made).
"git merge" is for merging branches you have (copies of) in the same
repository. There's also "git fetch" for getting local copies of branches
(and tags) elsewhere, and "git pull" does a "fetch" and a "merge", with
the ability to put the information only in a temporary location in
between.
What part of the documentation confused you? It probably needs to be
clarified.
