And that can be as simple (or ugly, not sure if its buggy) as:

debugfs_create_unsigned_long()
{
        if (sizeof(unsigned long) == sizeof(u32))
                return debugfs_create_u32();
        if (sizeof(unsigned long) == sizeof(u64))
                return debugfs_create_u64();

        return -EINVAL;
}
