[PATCH v2 5/5] docs: stable-kernel-rules: create special tag to flag 'no backporting'

[Thorsten Leemhuis]

Document a new variant of the stable tag developers can use to make the
stable team's tools ignore a change[1].

That way developers can use 'Fixes:' tags without fearing the changes
might be backported in semi-automatic fashion. Such concerns are the
reason why some developers deliberately omit the 'Fixes:' tag in
changes[2] -- which somewhat undermines the reason for the existence of
that tag and might be unwise in the long term[3].

A patch to make one of the stable-script honor the flag can be found in
https://lore.kernel.org/all/655ce2a3-eb04-4ade-999e-23fc5dc5fb3a@xxxxxxxxxxxxx/

For autosel I was unable to locate the code.
