current.stp cause kernel panic

[Wenji Huang]

Hi,

Due to some updates on kernel/sched.c and sched_idletask.c,  
testsuite/systemtap.stress/current.exp causes kernel panic again(i686, 
2.6.24-rc3)

I explored the detail,  the point is in 
kernel.function("*@kernel/sched.c").call, after searching the matched 
points, put_prev_task_idle is one of them. But it causes kernel panic.

Regards,
Wenji
