WTF: patch "[PATCH] ARC: export kmap" was seriously submitted to be applied to the 4.7-stable tree?

The patch below was submitted to be applied to the 4.7-stable tree.

I fail to see how this patch meets the stable kernel rules as found at Documentation/stable_kernel_rules.txt.

I could be totally wrong, and if so, please respond to <[email protected]> and let me know why this patch should be applied. Otherwise, it is now dropped from my patch queues, never to be seen again.

thanks,

greg k-h
