[RFC PATCH 2/2] check safety in stop_machine_run

[Masami Hiramatsu]

Hi,

This patch contains full set of a djprobe patch for linux-2.6.12 that 
uses stop_machine_run() to check safety of all cpus. This method has 
some performance issues.
- It must create threads for each CPU.
- It might sleep.
- If we want to insert a number of probes (this is usual situation in 
the module initialization), we must wait completion of all insertion.

So, I think this is an optional method of check routine.
