from the Linux kernel source:
http://lxr.free-electrons.com/source/kernel/sched/core.c#L3456:
/*
2042 * context_switch - switch to the new MM and the new
2043 * thread's register state.
2044 */
2045 static inline void
2046 context_switch(struct rq *rq, struct task_struct *prev,
2047 struct task_struct *next)
i am not so good on arch detail...perhaps you have ideas what
"thread's register state" is?
