[PATCH V2 0/3] sched: idle_balance() cleanup and fix

[Daniel Lezcano]

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.
