    SubjectRe: [PATCH v5 4/8] x86/mm/tlb: Flush remote and local TLBs concurrently
    Given that the last patch killed the last previously existing
    user of on_each_cpu_cond_mask there are now the only users.

    > if (info->freed_tables) {
    > - smp_call_function_many(cpumask, flush_tlb_func,
    > - (void *)info, 1);
    > + on_each_cpu_cond_mask(NULL, flush_tlb_func, (void *)info, true,
    > + cpumask);

    ..

    > + on_each_cpu_cond_mask(NULL, flush_tlb_func, (void *)info, true,
    > + cpumask);

    Which means the cond_func is unused, and thus on_each_cpu_cond_mask can
    go away entirely in favor of on_each_cpu_cond.
