[PATCH 1/4] i386: Fix modpost warning in SMP trampoline code

[Vivek Goyal <vgoyal@in.ibm.com>]

o MODPOST generates warning for i386 if kernel is compiled with 
  CONFIG_RELOCATABLE=y

WARNING: vmlinux - Section mismatch: reference to .init.text:startup_32_smp
from .data between 'trampoline_data' (at offset 0xc0519cf8) and 'boot_gdt'

o trampoline code/data can go into init section is CPU hotplug is not 
  enabled.
