x86: Introduce text_poke_smp_batch() for batch-code modifying
Introduce text_poke_smp_batch(). This function modifies several
text areas with one stop_machine() on SMP. Because calling
stop_machine() is heavy task, it is better to aggregate
text_poke requests.
( Note: I've talked with Rusty about this interface, and
he would not like to expand stop_machine() interface, since
it is not for generic use. )
