Maybe we could add COMPILE_TEST to the version string too?
Just to detect such kernels fast in user bug reports...

What kind of bug report are you going to get?

User manages to enable CONFIG_FOO by selecting COMPILE_TEST and
complains that it does not work. :)

These drivers are typically drivers for some SoC peripheral and the device will simply physically not exist on a platform that does not provide HAS_IOMEM. This is not really any
different from making the driver selectable via COMPILE_TEST for any other platform. To hit the issue you'd have to instantiate a device driver instance for a device that
physically does not exist. This will always result in a failure.

Okay, you have convinced me. :)

After search the history patches, I found one related patch which made
by myself (when I am in Asianux):

  "https://lkml.org/lkml/2013/7/1/641"

For me, it is a long discussion, and forced many members have to join
in. Please help check again.

Thanks.

OK, thank all of you, and I shall send the related patch for it. 

I will try to finish it within this week.
