Subject[PATCH] x86: fix section mismatch warning in topology.c
Date
Fix following warning:
WARNING: arch/x86/kernel/built-in.o(__ksymtab+0x2b0): Section mismatch: reference to .cpuinit.text:arch_register_cpu in '__ksymtab_arch_register_cpu'

Annotating exported symbols are wrong.
Previously the warning were hidden by avoiding the export
in the non HOTPLUG_CPU case but the improved checks in
modpost caught it anyway.
Fix it by removing the __cpuinit annotation and rearrange the
code a bit to save one ifdef/endif pair.
