However with the introduction of ACPI LPI support, this will be used from cpuhotplug path in ACPI processor driver. This patch drops the __init annotation from arm_cpuidle_init to avoid the following warning: WARNING: vmlinux.o(.text+0x113c8): Section mismatch in reference from the function acpi_processor_ffh_lpi_probe() to the function .init.text:arm_cpuidle_init() The function acpi_processor_ffh_lpi_probe() references the function __init arm_cpuidle_init(). This is often because acpi_processor_ffh_lpi_probe lacks a __init annotation or the annotation of arm_cpuidle_init is wrong.
