This patch fixes section mismatch warnings in smpboot_setup_io_apic(). WARNING: arch/x86/kernel/built-in.o(.text+0x11781): Section mismatch in reference from the function smpboot_setup_io_apic() to the function .init.text:setup_IO_APIC() The function smpboot_setup_io_apic() references the function __init setup_IO_APIC(). This is often because smpboot_setup_io_apic lacks a __init annotation or the annotation of setup_IO_APIC is wrong.
