Initially, the whole Hyper-V support code was a module (what's now in drivers/hv/) but then some core functionallity was moved out to arch/x86/ but we didn't add a new config back then. Still suffering :-) Ideally, we would want to have CONFIG_HYPERV_GUEST=y/n for what's in arch/x86/ (just like CONFIG_KVM_GUEST) CONFIG_HYPERV_VMBUS=y/n/m for what's in drivers/hv -- Vitaly
