on i386:

ld: drivers/vhost/vdpa.o: in function `vhost_vdpa_init':
vdpa.c:(.init.text+0x52): undefined reference to `__vdpa_register_driver'
ld: drivers/vhost/vdpa.o: in function `vhost_vdpa_exit':
vdpa.c:(.exit.text+0x14): undefined reference to `vdpa_unregister_driver'



drivers/virtio/vdpa/ is not being built. (confusing!)

CONFIG_VIRTIO=m
# CONFIG_VIRTIO_MENU is not set
CONFIG_VDPA=y
CONFIG_VDPA_MENU=y
# CONFIG_VDPA_SIM is not set
CONFIG_VHOST_IOTLB=y
CONFIG_VHOST_RING=m
CONFIG_VHOST=y
CONFIG_VHOST_SCSI=m
CONFIG_VHOST_VDPA=y

Full randconfig file is attached.

(This same build failure happens with today's linux-next, Mar. 31.)

@Yamada-san:  Is this a kbuild problem (or feature)?
