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. (link: https://lists.nongnu.org/archive/html/qemu-devel/2016-05/msg04188.html) 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.
