You are now duplicating these "ids" in different places in the kernel,
perhaps you should put them in one place (hyperv.h?) and then reference
them that way?  It's like a device id for pci, once you use it in two
places, it goes into pci_ids.h.

I'm not going to reject this patch, but can you please do this in a
follow-on patch?

thanks,
