This patch series enables a new method for live migration, i.e. software
assisted live migration. This patch provides a device argument for user
to choose the methold.
When "swlm=1", driver/device will do live migration with a relay thread
dealing with dirty page logging. Without this parameter, device will do
dirty page logging and there's no relay thread consuming CPU resource.

The patch looks good, except that I don't like the "swlm" name.
Maybe we could have something less obscure, even if a little bt longer?
What about "sw-live-migration"?
