Yes, the processor properties are associated with the cpu device object.

Each processor will have a cpu device object, with the device object UDI 
being differentiated with the cpu id. Under each device object, it will 
have its associated processor properties.

Set* methods will not be called on each processor. It applies for all 
the processors. No implications wrt massive coring/threading
