From a2b07664f6cd14836ff84a77f48566673dca00bb Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 24 Mar 2010 21:48:31 +0100 Subject: [PATCH] KVM: PPC: Make build work without CONFIG_VSX/ALTIVEC The FPU/Altivec/VSX enablement also brought access to some structure elements that are only defined when the respective config options are enabled. Unfortuately I forgot to check for the config options at some places, so let's do that now. Unbreaks the build when CONFIG_VSX is not set.
