The patch looks reasonable, but the description you have below the ---
should be the actual changelog that is missing.

Also, please show how you found this, did it trigger some checking tool,
or did you find it through manual inspection?

With that fixed,

Did you see my 'Acked-by' reply? When you a reply like that,
you should normally add that tag below your 'Signed-off-by'
so it doesn't get lost.

Other than that, I think you should write a changelog text above
about how you discovered it and why it should be done like this.

I am sorry, my answer was misplaced (wrong reply-to), I will resend a
new version of all the patchset with complete changelog. I am just
waiting for a ack/nack on the mce one.
