After having a closer look, the statement above does not enable VFIO KVM
device on book3s but does for everything else:
common-objs-$(CONFIG_KVM_VFIO) += $(KVM)/vfio.o
[...]
kvm-e500-objs := \
$(common-objs-y) \
[...]
kvm-objs-$(CONFIG_KVM_E500V2) := $(kvm-e500-objs)
[...]
kvm-e500mc-objs := \
$(common-objs-y) \
[...]
kvm-objs-$(CONFIG_KVM_E500MC) := $(kvm-e500mc-objs)
[...]
kvm-book3s_32-objs := \
$(common-objs-y) \
[...]
kvm-objs-$(CONFIG_KVM_BOOK3S_32) := $(kvm-book3s_32-objs)
This is becaise CONFIG_KVM_BOOK3S_64 does not use "common-objs-y":
kvm-objs-$(CONFIG_KVM_BOOK3S_64) := $(kvm-book3s_64-module-objs)
So I will keep vfio.o in the "common-objs-y" list and add:
+kvm-book3s_64-objs-$(CONFIG_KVM_VFIO) += \
+ $(KVM)/vfio.o
