[PATCH 2/5] Convert some functions to __init to avoid MODPOST warnings

[PATCH 2/5] Convert some functions to __init to avoid MODPOST warnings

[Vivek Goyal]

o Some functions which should have been in init sections as they are called
  only once. Put them in init sections. Otherwise MODPOST generates warning
  as these functions are placed in .text and they end up accessing something
  in init sections.

WARNING: vmlinux - Section mismatch: reference to .init.text:migration_init
from .text between 'do_pre_smp_initcalls' (at offset 0xc01000d1) and
'run_init_process'
