[Qemu-devel] [PATCH V3 0/7] cpu/acpi: convert cpu hot plug to hotplug_handler API

[Gu Zheng]

Previously we use cpu_added_notifiers to register cpu hotplug notifier callback
which is not able to pass/handle errors, so we switch it to unified hotplug
handler API which allows to pass errors and would allow to cancel device_add
in case of error.
Thanks very much for Igor's review and suggestion.

v3:
 -deal with start-up cpus in pc_cpu_plug as Igor suggested.

v2:
 -Add 3 new patches(5/7,6/7,7/7), delete original patch 5/5.
  1/5-->1/7
  2/5-->2/7
  3/5-->3/7
  4/5-->4/7
 Patch 1/7:
 -add errp argument to catch error.
 -return error instead of aborting if cpu id is invalid.
 -make acpi_cpu_plug_cb as a wrapper around AcpiCpuHotplug_add.
 Patch 3/7:
 -remove unused AcpiCpuHotplug_add directly.
 Patch 5/7:
 -switch the last user of cpu hotplug notifier to hotplug handler API, and
  remove the unused cpu hotplug notify.
 Patch 6/7:
 -split the function rename (just cleanup) into single patch.
 Patch 7/7:
 -introduce help function acpi_set_local_sts to keep the bit setting in
  one place.

Gu Zheng (7):
  acpi/cpu: add cpu hotplug callback function to match hotplug_handler
    API
  acpi:ich9: convert cpu hotplug handle to hotplug_handler API
  acpi:piix4: convert cpu hotplug handle to hotplug_handler API
  pc: add cpu hotplug handler to PC_MACHINE
  pc: Update rtc_cmos in pc_cpu_plug
  cpu-hotplug: rename function for better readability
  acpi/cpu-hotplug: introduce help function to keep bit setting in one
    place
