Please do not top-post :(

Just resend your patch properly, in a format that we can apply it in,
and we will be glad to review and discuss it that way.

Look for thousands of examples on the lists for how to do this, as well
as the documentation in the kernel tree itself which explains this in
way-too-much detail.
