Subject: [PATCH v1 0/2] Fix CONFIG_HYPERV and vmbus related anamoly

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.

V1:
 o Change subject from hyper-v to "Drivers: hv:"
 o Rewrite commit messages paying attention to VMBus and not vmbus
 o Change some wordings in Kconfig
 o Make new VMBUS config option default to HYPERV option for a smoother
   transition

Mukesh Rathor (2):
  Driver: hv: Add CONFIG_HYPERV_VMBUS option
  Drivers: hv: Make CONFIG_HYPERV bool
