[PATCH] i386: fix modpost warning in SMP trampoline code

Browse Source 
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.
