Quite the system you have there :) What was once 760 lines has been reduced to 24 without removing any information.

This seems to be the most we can reduce this particular output since we don't support mapping multiple pxms to a single node.

Yes, thanks very much for the optimization.

(And you can add my Acked-by or whatever you need.)

Tomorrow I will have more time on the system and will try out all the
new changes together, mostly with summarizing the Processor stats.
