Fix following warning: WARNING: o-x86_64/arch/x86/kernel/built-in.o(.text+0x13d15): Section mismatch in reference from the function acpi_map_lsapic() to the function .cpuinit.text:mp_register_lapic()
The function acpi_map_lsapic() is exported and thus not annotated. But the sole user is acpi/processor_core.c in a __cpuinit path. So create a small wrapper and put back the annotation thus avoiding the warning.
