`index' has type u64.  You don't know what C type is used to implement
u64, hence it must be cast to a known type before it can be passed to
printk.

In this case we use `unsigned long long'.

The code as it stands will generate compiler warnings on some
architectures.

One day, maybe before we all die, we will fix this.  Then we get to
spend another five years weeding out all the casts we added.
