[PATCH v3 0/3] Fix memory leak of some device state in migration

[Jinhao Gao]

For some device state having some fields of VMS_ALLOC flag, they
don't free memory allocated for the fields in vmstate_save_state
and vmstate_load_state. We add funcs or sentences of free memory
before and after VM saves or loads device state to avoid memory leak.

v2
 - Drop patch1-3,6-8 of v1
 - Address Michael's comment (free memory before load vmsd centrally)
 - Add David's Acked-by and Michael's Signed-off-by

v3
 - Add Euler's Reported-by and Michael's Reviewed-by

Jinhao Gao (3):
  spapr_pci: Fix memory leak of vmstate_spapr_pci
  savevm: Fix memory leak of vmstate_configuration
  vmstate: Fix memory leak in vmstate_handle_alloc()
