At present, drivers/Makefile will subst =m to =y for CONFIG_HYPERV for hv subdir. Also, drivers/hv/Makefile replaces =m to =y to build in hv_common.c that is needed for the drivers. Moreover, vmbus driver is built if CONFIG_HYPER is set, either loadable or builtin.
This is not a good approach. CONFIG_HYPERV is really an umbrella config that encompasses builtin code and various other things and not a dedicated config option for VMBUS. Vmbus should really have a config option just like CONFIG_HYPERV_BALLOON etc. This small series introduces CONFIG_HYPERV_VMBUS to build VMBUS driver and make that distinction explicit. With that CONFIG_HYPERV could be changed to bool. For now, hv_common.c is left as is to reduce conflicts for upcoming patches, but once merges are mostly done, that and some others should be moved to virt/hyperv directory.
