From a7e73e711e48e138a25265c156cca9a1ed109b50 Mon Sep 17 00:00:00 2001 From: "Shreyas B. Prabhu" <shreyas@linux.vnet.ibm.com> Date: Thu, 16 Apr 2015 16:28:09 +0530 Subject: [PATCH] powerpc/kvm: Fix ppc64_defconfig + PPC_POWERNV=n build error kvm_no_guest() 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.
