Just move the whole "spin_or_schedule()" into sched.c, and you're all done. Yeah, that requires having sched.c know a bit about mutex locking rules, but the data structures are already exported in <linux/mutex.h>, and while _normal_ code should never care or know exactly how it is used, I think the scheduler might as well. Mutexes are clearly very much a scheduling entity, so it's not too much of a break with internal knowledge.
