[Qemu-devel] [PULL 16/16] target-i386: Move KVM default-vendor hack to instance_init |

From: Eduardo Habkost <address@hidden>
As we will not have a cpu_x86_find_by_name() function anymore,
move the KVM default-vendor hack to instance_init.
Unfortunately we can't move that code to class_init because it depends
on KVM being initialized.
