Ah, right.  I got confused.

kern/softirq.c has the followings.

 DEFINE_PER_CPU(struct list_head [NR_SOFTIRQS], softirq_work_list);
 EXPORT_PER_CPU_SYMBOL(softirq_work_list);

and it doesn't cause any warning on x86 neither does it on ia64 with
defconfig.  softirq_work_list doesn't trigger any warning there,
right?

Thanks.
