With the introduction of the ISA_BUS_API Kconfig option, ISA-style
drivers may be built for X86_64 architectures. This patch changes the
ISA Kconfig option dependency of the PC/104 drivers to ISA_BUS_API, thus
allowing them to build for X86_64 as they are expected to.

Greg K-H,

Would you be able to pick up this entire patchset via driver-core; I
figure that tree is the most appropriate to receive any core ISA bus
driver changes (unless you see a more fitting path to take).

[…]
Yes, I can take this through the driver core tree as that's where the
original series came from...

Was this series merged or did it fell through the cracks? I currently
assume the latter, as I can't see it in neither mainline nor linux-next
(but maybe I'm missing something). Just wondering, because I have this
issue on my regression list for 4.7.

For the whole context see:
http://thread.gmane.org/gmane.linux.kernel.gpio/17016/

Sincerely, your regression tracker for Linux 4.7 (http://bit.ly/28JRmJo)

I don't think this is a regression, I was going to queue these up for
4.8-rc1.  As it is now, 4.7-rc is working just fine in this regards,
right?

Or am I missing something?

The PC/104 drivers were changed to utilize the ISA bus driver as part of
the original patchset which attempted to decouple the X86_32 dependency
from the ISA Kconfig option; these drivers were updated with the
intention of building on X86_64 in addition to X86_32.

However, the respective patches were merged without the decoupling
changes (since decoupling was the wrong approach), resulting in an
unintentional regression: the PC/104 drivers are now restricted to
X86_32 due to the ISA Kconfig option dependency, while they were capable
of building for X86_64 in previous kernel versions.

This patchset should fix this regression by introducing the ISA_BUS_API
Kconfig option, and the respective Kconfig dependency changes for the
drivers, in order to allow them to build for both X86_64 and X86_32 as
originally capable.

Ah, ok, that makes more sense, thanks.  I'll go queue these up now.
