Please don't disable the VFIO device for the non-book3s case. I added
it (even though it didn't do anything until now) so that libvirt
wouldn't choke when it finds it's not available. Obviously the new
ioctl needs to be only for the right IOMMU setup, but the device
itself should be available always.
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_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
