Hi Greg,

After merging the driver-core tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from include/uapi/linux/stddef.h:1:0,

and on ...

Somehow caused by commit

8ac0fba2da41 ("isa: Decouple X86_32 dependency from the ISA Kconfig option")

I don't easily see why it causes the problem, but reverting it makes the
build work. I also cannot rule out interaction with some other tree.

I have reverted that commit for today.
