[Qemu-devel] [PATCH V4 0/8] cpu/acpi: convert cpu hot plug to hotplug_handler API |

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.
v4:
-split removal of CPU hotplug notifier into separate patch (Patch 6/8).
Patch 1/7:
-convert CPUState *cpu to DeviceState *dev like it's done for other handlers
and do cast to CPU inside.
Patch 5/7:
-Make rtc_state as a link property in PCMachine rather than the global
variables.
-Split out the removal of unused notifier into separate patch.
-Check the result of plug callback before update rtc_state.
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.
