[Vladimir Sementsov-Ogievskiy]

v7:
  02: Reviewed-by: Igor Mammedov
  04: object instead of dimm
  05: arror_abort instead of NULL for getting size property,
      remove superfluous include

v6:
 add stubbed pc_dimm_build_list, fix compilation for
 !CONFIG_MEM_HOTPLUG targets - thx to Cornelia.

v5: do not use qapi
 0002-0004: new patches
 0005: white list instead of black list

v4:
 0001: Reviewed-by: Eric Blake <address@hidden>
 second patch is splitted to 0002 and 0003
 0002: Add 'type' field instead of 'balloonable' to PCDIMMDeviceInfo
 0003: chec 'type' instead of 'balloonable'

v3:
    - do not use additional class variable

NVDIMM for now is planned to use as a backing store for DAX filesystem
in the guest and thus this memory is excluded from guest memory
management and LRUs.

In this case libvirt running QEMU along with configured balloon almost
immediately inflates balloon and effectively kill the guest as
qemu counts nvdimm as part of the ram.


Vladimir Sementsov-Ogievskiy (5):
  move get_current_ram_size to virtio-balloon.c
  pc-dimm: rename pc_dimm_built_list()
  pc-dimm: add pc_dimm_build_list()
  virtio-balloon: rewrite get_current_ram_size()
  balloon: Use only 'pc-dimm' type dimm for ballooning
