Mini-OS's printk doesn't add a 0x prefix for either %p or %lx, so
doing this would change the behaviour (which might be good, but I
don't think it should be part of this patch, which is only about
fixing the types).

- cast after >>, not before
- format STACK_SIZE as long
- avoid using %llu (which isn't implemented)
