The latest sched-devel.git tree can be pulled from:

git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched-devel.git

This is a quick iteration after yesterday's: a couple of group
scheduling bugs were found/debugged and fixed by Srivatsa Vaddagiri and
Mike Galbraith. There's also a yield fix from Dmitry Adamushko, a build
fix from S.Ceglar Onur and Andrew Morton, a cleanup from Hiroshi
Shimamoto and the usual stream of goodies from Peter Zijlstra. Rebased
it to -rc8 as well.

there are no known regressions at the moment in the sched-devel.git
codebase. (yay :)
