show_cacheinfo() needs to access the cacheinfo structure of any online cpu. This was done with using smp_processor_id() as in index while in preemtible context. This means the cpu could be offline and the data be gone when it would be accessed. Better use any online cpu address and protect the data by get_online_cpus() and put_online_cpus().
