This patch enables migrating vcpu's TSC rate. If KVM on the destination machine supports TSC scaling, guest programs will observe a consistent TSC rate across the migration. If TSC scaling is not supported on the destination machine, the migration will not be aborted and QEMU on the destination will not set vcpu's TSC rate to the migrated value. If vcpu's TSC rate specified by CPU option 'tsc-freq' on the destination machine is inconsistent with the migrated TSC rate, the migration will be aborted. For backwards compatibility, the migration of vcpu's TSC rate is disabled on pc-*-2.5 and older machine types.
