Vivek Goyal 4a5d107a9a [PATCH] i386: cpu hotplug/smpboot misc MODPOST warning fixes
o Misc smpboot/cpu hotplug path cleanups. I did those to supress the
  warnings generated by MODPOST. These warnings are visible only
  if CONFIG_RELOCATABLE=y.

o CONFIG_RELOCATABLE compiles the kernel with --emit-relocs option. This
  option retains relocation information in vmlinux file and MODPOST
  is quick to spit out "Section mismatch" warnings.

o This patch fixes some of those warnings. Many of the functions in
  smpboot case are __devinit type and they in turn accesses text/data which
  if of type __cpuinit. Now if CONFIG_HOTPLUG=y and CONFIG_HOTPLUG_CPU=n
  then we end up in cases where a function in .text segment is calling
  another function in .init.text segment and MODPOST emits warning.

WARNING: vmlinux - Section mismatch: reference to .init.text:identify_cpu from .text between 'smp_store_cpu_info' (at offset 0xc011020d) and 'do_boot_cpu'
WARNING: vmlinux - Section mismatch: reference to .init.text:init_gdt from .text between 'do_boot_cpu' (at offset 0xc01102ca) and '__cpu_up'
WARNING: vmlinux - Section mismatch: reference to .init.text:print_cpu_info from .text between 'do_boot_cpu' (at offset 0xc01105d0) and '__cpu_up'

o It also fixes the issues where CONFIG_HOTPLUG_CPU=y and start_secondary()
  is calling smp_callin() which in-turn calls synchronize_tsc_ap() which is
  of type __init. This should have meant broken CPU hotplug.

WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'start_secondary' (at offset 0xc011603f) and 'initialize_secondary'
WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'MP_processor_info' (at offset 0xc0116a4f) and 'mp_register_lapic'
WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'MP_processor_info' (at offset 0xc0116a4f) and 'mp_register_lapic'
