I'm a bit confused.  Why do we need to specify 6.14.x?  I would have
assumed that the Fixes tag was enough information.  What are we supposed
to see in the patch description?

I suspect you're making this too complicated...  Just put
Cc: <stable@xxxxxxxxxxxxxxx> and a Fixes tag and let the scripts figure
it out.  Or put in the commit description, "The Fixes tag points to
an older kernel because XXX but really this should only be backported
to 6.14.x because YYY."
