* remotes/ehabkost/tags/machine-next-pull-request:
  qom: Don't keep error value between object_property_parse() calls
  qdev: fix -device scsi-hd,help regression
  machine: Use shorter format for GlobalProperty arrays
  machine: Eliminate unnecessary stringify() usage
  spapr: Eliminate SPAPR_PCI_2_7_MMIO_WIN_SIZE macro
  memory-device: rewrite address assignment using ranges
  range: add some more functions
  Mention that QMP 'cpu-add' will be deprecated
  Update that HMP 'cpu-add' is deprecated in 4.0
  qemu-deprecated.texi: Rename the HMP section
