The cpu state should be synchronized when apic-id is available. Otherwise
the "info lapic " always returns stale data.

The fix is to break when it is time to come to the next block, so that both
'pfnptr' and 'blockptr' refer to the same block.

Since the old target server does not support pkru, I assume the VM's cpu type
should not support pkru. Therefore, the pkru should never be migrated away from
source server.

. Is there any issue with output format?
3. Is it fine to add only for HMP, but not QMP?
Thank you very much!

(e.g., via eventfd, MSI-X
or legacy IRQ).
The 'call' is to inject irq on purpose by admin for a specific device (e.g.,
vhost-scsi) from QEMU/host to VM, while the 'kick' is to kick the doorbell
on purpose by admin at QEMU/host side for a specific device.

Changed since RFC:
- add support for more virtio/vhost pci devices
- add log (toggled by DEBUG_VIRTIO_EVENT) to virtio.c to say that this
mischeivous command had been used
- fix grammer error (s/lost/loss/)
- change version to 6.1
- fix incorrect example in
