Subject: IO-mapping.txt and ISA memory space

Hi Linus,
We have isa_*() functions to access ISA memory space since a while.
I'm still missing isa_{request,release}_mem_region(), though.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
