    mm: refactor TLB gathering API · 56236a59
    Minchan Kim authored
    This patch is a preparatory patch for solving race problems caused by
    TLB batch.  For that, we will increase/decrease TLB flush pending count
    of mm_struct whenever tlb_[gather|finish]_mmu is called.
    
    Before making it simple, this patch separates architecture specific part
    and rename it to arch_tlb_[gather|finish]_mmu and generic part just
    calls it.
    
    It shouldn't change any behavior.
