What is the functional goal/purpose of adding CONFIG_ACPI_PROCESSOR_CSTATE?
Avoid adding unnecessary dummy implementations of functions and
variables that will never be used on ARM64 and also looks ugly IMO.
E.g.: arch_safe_halt
boot_option_idle_override
IDLE_NOMWAIT
acpi_unlazy_tlb
acpi_processor_cstate_check
disabled_by_idle_boot_param and more...
If the answer is that it saves code space on an ARM build, how much
space does it save?
NO, it doesn't even add a kB of code I believe, so that's definitely not
the reason. I am fine to retain if we can find a saner way to solve the
above issue.
