CPU core ID is used to index the core_data[] array. The core ID is, however, not
sequential; 10-core CPUS can have a core ID as high as 25. Increase the limit to
32 to be able to deal with current CPUs.

Looking forward, it would be great if we could get rid of this
arbitrary limit.

Agreed. I thought about dynamic allocation and a small hash table to
access it. If/when I have time ... or someone else, maybe.
