[RFC] ProcessorRASD, the class that won't go away
Around and round we go on the merry-go-round of indecision, hopefully for our last ride. The definitely probably absolutely tentative final plan is that the default representation of processors as virt_device structs will be one per domain, with a quantity. Virt_Devices will just need to be told how to handle that, and all the RASD stuff will be much happier for it. And then we will never speak of this again.
