I'm not sure I get what you're pointing at. Can you give one example?

Related observation: doing
    scripts/get_maintainer.pl -f drivers/pcmcia/m8xx_pcmcia.c --no-git-fallback --no-keywords

just gave me
    linux-pcmcia@...ts.infradead.org (open list:PCMCIA SUBSYSTEM)
    linux-kernel@...r.kernel.org (open list)

Note that there's no person responsible for PCMCIA. That's why I
included the people (and lists) maintaining PPC8XX and PPC.
