SubjectRe: BUG_ON(!cpus_equal(cpumask, tmp));
Hari,

I see code similar to what you are changing, also in the file:

	arch/x86_64/kernel/smp.c

Do your considerations apply here as well?

===

static void flush_tlb_others(cpumask_t cpumask, struct mm_struct *mm,
                                                unsigned long va)
{
        cpumask_t tmp;
	/* ... */
        BUG_ON(cpus_empty(cpumask));
        cpus_and(tmp, cpumask, cpu_online_map);
        BUG_ON(!cpus_equal(tmp, cpumask));
        BUG_ON(cpu_isset(smp_processor_id(), cpumask));
        if (!mm)
                BUG();
	/* ... */

                          I won't rest till it's the best ...
