parent[PATCH] Use ZVC for free_pages (diff)
[PATCH] Reorder ZVCs according to cacheline
The global and per zone counter sums are in arrays of longs. Reorder the ZVCs so that the most frequently used ZVCs are put into the same cacheline. That way calculations of the global, node and per zone vm state touches only a single cacheline. This is mostly important for 64 bit systems were one 128 byte cacheline takes only 8 longs.
