I am not smart enough to get the point. I have paid a lot of time for this patch, 
I need an result even it doesn't work. so i like the reply like this:

1. this patch is meaningless, and should be rejected.   
2. this issue is real, but we need other methond, not this patch.
3. the patch need to improve.

I don't want to say that the patch is meaningless ... it may be useful to you
in your environment to help sort out machine checks due to h/w issues vs.
programming errors in the machine check recovery code.

But I don't think it is generally useful in the upstream code.
