From: Uri Lublin <[EMAIL PROTECTED]>
The function kvm_cpu_register_physical_memory() does not keep phys_offset.
We need it when updating qemu-dirty-page-bitmap with kvm-dirty-page-bitmap.
Now (for VM RAM) start_addr would be the same as phys_offset.
Getting kvm-dirty-page-bitmap and updating qemu-dirty-bitmap would be
done correctly.
