From f24817716efe52f3c8fc137c6893963a0416f3cb Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Fri, 20 Sep 2013 14:52:42 +1000 Subject: [PATCH] KVM: PPC: Book3S PR: Fix compilation without CONFIG_ALTIVEC 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.
