Peter,
this patchset replace the beginning of the previous mixed one which was not yet commited [1] without changes except a compilation error fix for UP kernel config. It is refreshed against tip/sched/core.
As the UP config compilation is broken on the previous patchset, git bisect is no longer safe for it. You can apply this small serie and drop the 3 first patches of the previous series [1], or ignore it and I will bring the fix after you applied [1].
It cleanups the idle_balance function parameters by passing the struct rq only, fixes a race in the idle_balance function and finally move the idle_stamp from fair.c to core.c. I am aware it will return back to fair.c with Peter's pending patches but at least it changes the idle_balance() function to return true if a balance occured.
