Subject: linux-next: build failure after merge of the moduleh tree

Hi Paul,

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

arch/x86/kernel/nmi.c:195:1: warning: data definition has no type or storage class [enabled by default]

Caused by commit 9c48f1c629ec ("x86, nmi: Wire up NMI handlers to new
routines") from the tip tree interacting with the modul.h split up.

I have added the following patch for today.
