Hi ,

Patch needed, when CONFIG_HOTPLUG_CPU is enabled, in order to fix a 
compile error.

#ifdef CONFIG_HOTPLUG_CPU
static void lru_drain_cache(unsigned int cpu)
{
-       struct pagevec *pvec = &per_cpu(lru_add_pvecs, cpu);
+       struct pagevec *pvec = &per_cpu_var_locked(lru_add_pvecs, cpu);

       /* CPU is dead, so no locking needed. */
       if (pagevec_count(pvec))
               __pagevec_lru_add(pvec);
-       pvec = &per_cpu(lru_add_active_pvecs, cpu);

       if (pagevec_count(pvec))
               __pagevec_lru_add_active(pvec);
}

Otherwise, I get :

  CC      mm/swap.o

Hope this help,
