    x86: Introduce text_poke_smp_batch() for batch-code modifying · 7deb18dc
    Masami Hiramatsu authored
    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. )
