[Qemu-ppc] [QEMU PATCH v6 0/2] migration: migrate QTAILQ

[Jianjun Duan]

v6: - Split from Power specific patches. 
    - Dropped VMS_LINKED flag.
    - Rebased to master.
    - Added comments to clarify about put/get in VMStateInfo.  

Previous versions are:

v5: - Rebased to David's ppc-for-2.8. 
(link: https://lists.nongnu.org/archive/html/qemu-devel/2016-10/msg00270.html)

v4: - Introduce a way to set customized instance_id in SaveStateEntry. Use it
      to set instance_id for DRC using its unique index to address David 
      Gibson's concern.
    - Rename VMS_CSTM to VMS_LINKED based on Paolo Bonzini's suggestions.
    - Clean up qjson stuff in put_qtailq. 
    - Add trace for put_qtailq and get_qtailq based on David Gilbert's 
      suggestion.
    - Based on David's ppc-for-2.7.

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.
