What does this represent here? I'm pretty sure it is meaningless to the
upstream kernel, so please get rid of it.

Since Stan is the original author of this and following patches, there
should be a s-o-b tag from him. After that you should add yours
indicating that you are carrying the patches from Stan.

Also, please add a cover letter stating the purpose of this series, how
it is tested, and with any other relevant information.

Thanks,
Mani
