[PATCH] generic: Break init() in two parts to avoid MODPOST warnings
o init() is a non __init function in .text section but it calls many
functions which are in .init.text section. Hence MODPOST generates lots
of cross reference warnings on i386 if compiled with CONFIG_RELOCATABLE=y
WARNING: vmlinux - Section mismatch: reference to .init.text:smp_prepare_cpus from .text between 'init' (at offset 0xc0101049) and 'rest_init'
WARNING: vmlinux - Section mismatch: reference to .init.text:migration_init from .text between 'init' (at offset 0xc010104e) and 'rest_init'
WARNING: vmlinux - Section mismatch: reference to .init.text:spawn_ksoftirqd from .text between 'init' (at offset 0xc0101053) and 'rest_init'
o This patch breaks down init() in two parts. One part which can go
in .init.text section and can be freed and other part which has to
be non __init(init_post()). Now init() calls init_post() and init_post()
does not call any functions present in .init sections. Hence getting
rid of warnings.
