Add savevm/loadvm support for MCE
Port qemu-kvm's
commit 1bab5d11545d8de5facf46c28630085a2f9651ae
Author: Huang Ying <ying.huang@intel.com>
Date: Wed Mar 3 16:52:46 2010 +0800
Add savevm/loadvm support for MCE
MCE registers are saved/load into/from CPUState in
kvm_arch_save/load_regs. To simulate the MCG_STATUS clearing upon
reset, MSR_MCG_STATUS is set to 0 for KVM_PUT_RESET_STATE.
