Actually, a better fix is to just make arch/i386/mm/fault.c include
"<linux/interrupt.h>" like it should.

It so happens that on SMP it wasn't strictly necessary (the SMP header
files almost by mistake happen to do the proper includes), so I never
noticed. But because fault.c uses "in_interrupt()" is should definitely
include <linux/interrupt.h>.
