kvm_no_guest function calls power7_wakeup_loss to put the thread into the deepest supported idle state. power7_wakeup_loss is defined in arch/powerpc/kernel/idle_power7.S, which is compiled only when PPC_P7_NAP=y. And PPC_P7_NAP is selected when PPC_POWERNV=y. Hence in cases where PPC_POWERNV=n and KVM_BOOK3S_64_HV=y we see the following error:
arch/powerpc/kvm/built-in.o: In function `kvm_no_guest': arch/powerpc/kvm/book3s_hv_rmhandlers.o:(.text+0x42c): undefined reference to `power7_wakeup_loss'
Fix this by adding PPC_POWERNV as a dependency for KVM_BOOK3S_64_HV.
