 *
 *  Create arrays for initializing the kernel folded tables (using a hash
 *  table turned out to be to limiting...)  Unfortunately we can't simply
 *  preinitialize the tables at compile time since kfree() cannot accept
 *  memory not allocated by kmalloc(), and doing our own memory management
 *  just for this seems like massive overkill.
