Currently x86 is the only architecture that uses kvm_guest_init(). With PowerPC we're getting a second user, but the signature is different there and we don't need to export it, as it uses the normal kernel init framework. So let's move the x86 specific definition of that function over to the x86 specfic header file. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
