Some older (~2.6.7) kernels write MCG_STATUS register during kernel boot (mce_clear_all() function, called from mce_init()). It's not currently handled by kvm and will cause it to inject a GPF. Following patch adds a "nop" handler for this. Signed-off-by: Sergey Kiselev <sergey.kiselev@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
