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,
                 from include/linux/stddef.h:4,

             ^

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.

The PnP errors are due to an overly broad Kconfig dependency list, and
are resolved with the following patch:
<https://lkml.org/lkml/2016/5/1/100>. This patch should be applied first
to prevent the PnP build for X86_64, when the X86_32 dependency is
decoupled from the ISA Kconfig option in this current patch.

See <https://lkml.org/lkml/2016/4/11/421> for the history behind these
two patches.

You didn't tell me that when I applied the above patch :(

I'll go apply the pnp patch now, but really, please be more careful with
dependancies next time.
