    They are still very much there, unchanged for a long time and
    acked by everyone - I thought I'd spare a few electrons by not
    doing a 60+ patches full resend.

    Here is how it looks like in the full diffstat:

    Rik van Riel (6):
    mm/generic: Only flush the local TLB in ptep_set_access_flags()
    x86/mm: Only do a local tlb flush in ptep_set_access_flags()
    x86/mm: Introduce pte_accessible()
    mm: Only flush the TLB when clearing an accessible pte
    x86/mm: Completely drop the TLB flush from ptep_set_access_flags()
    sched, numa, mm: Add credits for NUMA placement

    I'm really fond of these btw., they make a real difference.

    Thanks,

    Ingo
