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).
