[PATCH 0/2] sched: SCA vs hotplug vs stopper races fixes

[Valentin Schneider]

Hi folks,

This is the continuation of [1]. As Will noted, that patch isn't sufficient to
plug all the nasty races involving SCA, hotplug and the stopper task, hence
patch 2.

I have to apologize as this didn't see much testing (a CPU hog, a crazed
taskset, and some hotplugs in a loop), and unfortunately I need to call it a day
before running away to the british wilderness 'till Monday. I'll get back to it
then to expunge the remaining daftness.

Cheers,
Valentin
