Yeah, this looks like a pretty good start - this is roughly the approach i 
outlined to Stephane and Andi, generic cache events extended with one more 
'node' level.

Andi, Stephane, if you'd like to see the Intel offcore bits supported in 2.6.40 
(or 2.6.41) please help out Peter with review, testing, tools/perf/ 
integration, etc.

Thanks,
