It is part of the init code for the crc32 module in the kernel:

static int __init crc32c_sparc64_mod_init(void)
{
        if (sparc64_has_crc32c_opcode()) {
                pr_info("Using sparc64 crc32c opcode optimized CRC32C implementation\n");
                return crypto_register_shash(&alg);
        }
        pr_info("sparc64 crc32c opcode not available.\n");
        return -ENODEV;
}

So expect to see it only when the module is loaded - likely during boot.
