From e4ab0d6b0d1118a90238d8194eedb91aab15ebe1 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Fri, 2 Nov 2012 14:25:15 -0200 Subject: [PATCH] target-i386: cpu: fix --disable-kvm compilation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fixes the following: target-i386/cpu.o: In function `kvm_cpu_fill_host': target-i386/cpu.c:783: undefined reference to `kvm_state' I didn't notice the problem before because GCC was optimizing the entire kvm_cpu_fill_host() function out (because all calls are conditional on kvm_enabled()). * cpu_x86_fill_model_id() is used only if CONFIG_KVM is set, so #ifdef it entirely to avoid compiler warnings. * kvm_cpu_fill_host() should be called only if KVM is enabled, so use #ifdef CONFIG_KVM around the entire function body.
