Wondering if the following patch is helpful on your Xeon server?

Btw, you can run vmstat as background tool or use 'perf sched'
to get scheduler statistics change for this patchset.

The following are results of original kernel and all 5 patches 
on pandaboard ES.

    latest kernel 527d1511310a89        + this patchset
