Which reminds me...

One spirited side discussion at Santa Fe involved RCU's rcu_node tree
and CPU numbering.  Several people insisted that RCU should remap CPU
numbers to allow for interesting CPU-numbering schemes.  I resisted
this added complexity rather strenuously, but eventually said that I
would consider adding such complexity if someone provided me with valid
system-level performance data showing a need for this sort of remapping.

I haven't heard anything since, so I figured that I should follow up.
How are things going collecting this data?
