sparse breakage triggered by rcu_read_lock() lockdep annotations

sparse: flow.c:805: rewrite_parent_branch: Assertion `changed' failed.
There is a apparently an upstream patch to the latest sparse that fixes this. I
built a sparse package with the 2007-10-22 nightly tarball and it seems to work.
This is the only link to the upstream discussion on this that I could find:
