Dear Linux folks,


Building the latest master branch from Linus, commit 0e271fd59fe9
(Merge tag 'platform-drivers-x86-v4.14-1' of
git://git.infradead.org/linux-platform-drivers-x86) fails with the error
below. The same development environment worked up to the release of 
Linux
4.13.

```

The same error is mentioned in the review of a patch in September 2016 
[1],
and, indeed, I am build *for* a 32-bit system, `CONFIG_X86_32=y`, *on* a 
64-bit system.


Kind regards,

Paul
