F.e. Someone is loading lots of modules with lots of percpu data. This will currently fail if there are more than 8000 bytes allocated. With the percpu option the size can be configured on bootup. A minor thing but the allocator can later be used for other things. See the full cpu alloc patchsets that have been posted before (last one in May).
