The new tuning would be the 8->32 patch - but that would be a more complex and
separate (and definitely controversial) patch anyway.

So if hpa gives his ack we can try this current spread-tlb-vectors-better patch in
-tip and see how it fares. Could you please update the changelog to specify the 20%
improvement more precisely? What kind of workload was used and how was the
improvement measured?

Thanks,

Ingo
