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
