I asked the preprocessor to tell me why I didn't hit this in my tree. Seems
it because vmalloc.h is included in my tree through the following includes. 

./include/linux/nmi.h
./arch/x86/include/asm/nmi.h
./arch/x86/include/asm/io.h
./include/asm-generic/io.h
./include/linux/vmalloc.h

Such paths may not exist in kbuild robot's tree, so I will apply Vlad's patch to
fix this and push it to my rcu/kfree branch.

thanks,
