Subject: Re: [PATCH v2 2/3] Documentation, ABI: Add a document entry for
 cache id

Yeah, so if the 'cache index' naming has already been settled, then I suspect 
we'll have to live with it - but at least let's name it 'cache-index' when we 
refer to it, not just 'index' which is super confusing (to me!).

I.e. instead:

  The id identifies a cache in the platform. In same index, the id
  is unique across the platform.

Something like this is more readable I think:

  The cache-id identifies a hardware cache of the system within a given
  cache-index category of caches. The (cache-index,cache-id) pair is
  unique for the whole system.

agreed?

Thanks,

	Ingo
