Hi,

This series is a follow-up of the existing change in ppc-for-6.0
branch in David's tree, where the pSeries machine is now detecting
one case in which the memory hotunplug is rejected by the guest kernel.

Initially I would like to also add a QAPI event to report a CPU unplug
error, but we don't have this event available yet. Next time.



Daniel Henrique Barboza (5):
  spapr.c: assert first DRC LMB earlier in spapr_memory_unplug_request()
  spapr.c: check unplug_request flag in spapr_memory_unplug_request()
  spapr.c: add 'unplug already in progress' message for PHB unplug
  spapr_pci.c: add 'unplug already in progress' message for PCI unplug
  spapr.c: send QAPI event when memory hotunplug fails
