Roman, First, let me thank you. Broadly, this patch-set can be broken into 1. Moving existing definitions around - (to make it possible to share these between Hyper-V guest drivers and KVM) 2. Cleanup of the existing code in the VMBUS driver (under drivers/hv). To the extent possible, I want to take all non-KVM code through Greg's tree. We can then modify the KVM code to use these common definitions. Currently, I too am working on restructuring VMBUS driver code to fully isolate all x86 dependencies. I can work with you on integration as I too am moving things around. Regards, K.
