It turns out acpi_processor_power_init() get called two time in acpi_processor_add and acpi_processor_start.

Found several lines are duplicated in those two functions even related commit move them.

The related patches are ok.  Not sure how it could happen, looks like git problem.

-v2: add back acpi_processor_load_module(pr) to acpi_processor_load_start
