This driver has a #include <linux/nmi.h>

But inside that file it says:

#if defined(CONFIG_HAVE_NMI_WATCHDOG)
#include <asm/nmi.h>
#endif

and the randconfig used doesn't set CONFIG_HAVE_NMI_WATCHDOG


Some options:

1) Drop that #ifdef from <linux/nmi.h>
It was introduced as part of this commit:
f2e0cff85ed1 ("kernel/watchdog: introduce arch_touch_nmi_watchdog()")
presumably for some good reason.

2) Make this edac driver select CONFIG_HAVE_NMI_WATCHDOG
Yuck!

3) Make this driver #include <asm/nmi.h> instead of <linux/nmi.h>
This fixes this build error, but I thought that general policy was to
use the <linux/*.h> if it exists rather than the <asm/*.h> one.
Maybe that's ok here because this is an x86 specific driver?

I'm leaning toward option #3.
