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
