As message in commit 7df676974359 ("mm/memory.c: Update local TLB
if PTE entry exists") said, we should update local TLB only on the
second thread. So in the do_anonymous_page() here, we should use
update_mmu_tlb() instead of update_mmu_cache() on the second thread.


Maybe mention here "This only affects performance, but not correctness."

Oh, this is better. Hi Andrew, do I need to resend the v4?


I assume he can squash it, most probably no need to resend. :)

Got it. Both are fine for me. :)
