Yeah, I think Peter pointed this out before: why is the local variable 
still named 'pkg' when we now have a die ID?

The other patches have such problems too: when new facilities are 
introduced and used then function names and variable names need to be 
harmonized. Makes for rather confusing code otherwise, which invites bugs 
down the road.

There's many such instances left in this series, please review the whole 
patchset for such problems.

Thanks,

	Ingo
