Commit 9d1ffdd8f3 ("KVM: PPC: Book3S PR: Don't corrupt guest state when kernel uses VMX") added a call to kvmppc_load_up_altivec() that isn't guarded by CONFIG_ALTIVEC, causing a link failure when building a kernel without CONFIG_ALTIVEC set. This adds an #ifdef to fix this. Signed-off-by: Paul Mackerras <paulus@samba.org> --- arch/powerpc/kvm/book3s_pr.c | 2 ++ 1 file changed, 2 insertions(+)
