Please provide this type of information in the changelog section.

If you want something backported to older stable kernels, add a:
	Cc: stable <stable@kernel.org>
to the signed-off-by area of the patch and it will be automatically sent
to the stable alias when it gets included in Linus's tree so I know to
pick it up then.

Care to resend all of these patches based on these comments?
