This patch fixes guest reboot errors when using KVM. There are two issues when rebooting a guest using KVM 1. When the guest initiates a reboot the host is unable to stop the vcpu 2. When running a SMP guest the qemu monitor system_reset causes a vcpu crash This can be fixed by clearing the CSR values at reset and syncing the MPSTATE with the host.
