Both acpi_processor_get_info and acpi_processor_remove functions have architecture dependent functionality enabled via CONFIG_ACPI_HOTPLUG_CPU. Current pre-processor guards are restricting too much of functionality which makes it dificult to integrate other features such as Virtual CPU hotplug/unplug for arm64. This series, applied on top of v6.9-rc3, suggests a refactoring on these two functions with the intent to understand them better and hopefully ease integration of more functionality. Apart from patches 2/4 and 3/4, which could be squashed but left them separated intentionally so it would ease reviewing, changes are self-contained. So far I've boot tested it successfully alone and as a prefix for vCPU hotplug/unplug patches [1], on arm64.
