That's right. The last patch on this repo is:

	53b881888d7b (origin/master, origin/HEAD) check_or_vs_and: ignore the kernel's min/max macros

And the patch that adds -Wpointer-arith applies cleanly at the top of
it.

That's wrong.

Sparse nowadays are getting updates on this dir:

		url = git://git.kernel.org/pub/scm/devel/sparse/chrisl/sparse.git

I still track the old repo. My config for it is:

[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
[remote "origin"]
	url = git://git.kernel.org/pub/scm/devel/sparse/sparse.git
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master
[remote "sparse-chris"]
	url = git://git.kernel.org/pub/scm/devel/sparse/chrisl/sparse.git
	fetch = +refs/heads/*:refs/remotes/sparse-chris/*
