Since commit 82ed223c264def2b15ee4bec2e8c3048092ceb5f ("iomap: make IOPORT/PCI
mapping functions conditional"), ioport_map() is only available on platforms
that set HAS_IOPORT.

How can ISA be set if HAS_IOPORT is not? This shouldn't be allowed.

It's always been like that. With CONFIG_ISA, we have inb() and friends. But not
ioport_map(), which was introduced more recently.

OK, fair enough. Patch applied, thanks.

Any chance it will finds its way in 3.1, since it's still breaking
m68k allmodconfig
builds.

when I'm talking to journalists I just say "programmer" or something like that.
