the queue with your enhancements and simplifications applied looks good here, and it booted fine on two testboxes. I've updated the sched-devel.git tree: git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched-devel.git (below is the full shortlog over current upstream.) (I have not tested the group scheduling bits but perhaps Srivatsa would like to do that?)
