It is not.

hp2:/usr/src/25> grep -ri Depends-on Documentation | wc -l 
0

But it is!

hp2:/usr/src/25> grep -ri Depends-on ../gitlog | wc -l    
156

I actually removed it because a) various tools whine at me and b) we
didn't cc:stable anyway.

Please let's not add new metadata without having told others what that
metadata means?

"Fixes:" should be sufficient.  I interpret Fixes: as "apply this to any
kernel which contains <that>".  Is more needed?
