This should instead be

kvm-objs-$(CONFIG_PCI) += pci.o

I think this makes sense as we aren't about to do PCI passthrough support anyway if the host kernel doesn't support PCI (no vfio-pci, etc).   This will quiet the kernel test robot complaints about CONFIG_PCI_NR_FUNCTIONS seen on the next patch in this series.

hum, then you will need more than this to put all pci references in priv.c and kvm-s390.c away.


  obj-$(CONFIG_KVM) += kvm.o
