Support the request for vm's unused page information, response with
a page bitmap. QEMU can make use of this bitmap and the dirty page
logging mechanism to skip the transportation of these unused pages,
this is very helpful to speed up the live migration process.

The implementation of the current virtio-balloon is not very

This patch set contains two parts of changes to the virtio-balloon.
One is the change for speeding up the inflating & deflating process,
the main idea of this optimization is to use bitmap to send the page

virtio data transmission

When a TCE table (sPAPR IOMMU context) is in disabled state (which is true
by default for the 64-bit window), it has tcet->nb_table == 0 and
