v3: - Simplify overall design followng discussion with Paolo. No longer need
metadata to migrate QTAILQ.
- Extend VMStateInfo instead of adding similar fields to VMStateField.
- Clean up macros in qemu/queue.h.
v2: - Introduce a general approach to migrate QTAILQ in qemu/queue.h.
- Migrate signalled field in the DRC state.
- Put the newly added migrating fields in subsections so that backward
migration is not broken.
- Set detach_cb field right after migration so that a migrated hot-unplug
event could finish its course.

v1: - Inital version.
(link: https://lists.nongnu.org/archive/html/qemu-devel/2016-04/msg02601.html)
To make guest device (PCI, CPU and memory) hotplug work together
with guest migration, spapr drc state needs be transmitted in
migration. This patch defines the VMStateDescription struct for
spapr drc state to enable it.
To fix the potential racing between hotplug events on guest and
guest migration, ccs_list and pending_events of spapr state need be
transmitted in migration. This patch also takes care of it.
Alexey Kardashevskiy (1):
vmstate: Define VARRAY with VMS_ALLOC
Jianjun Duan (5):
Migration: Defined VMStateDescription struct for spapr_drc
Migration: extend VMStateInfo
Migration: migrate QTAILQ
Migration: migrate ccs_list in spapr state
Migration: migrate pending_events of spapr state
