Does the amd64 kernel know anything about which memory is attached to 
which processor, and which i/o bus is attached to which hypertransport link?
Can it use this information to do things like allocate pages to a process from 
the memory that is physically attached to the cpu upon which the process is 
running?  Along these lines, is there any way to set affinity between a process 
and a cpu (or set of cpu's in the case of multicore)?

Likewise with i/o devices, if a process or device driver wants to operate a 
particular device, can it be set to run on the cpu that owns the hypertransport 
connection upon which the device is connected?

thanks, 
ron.
