Andrew Morton e236a166b2 [PATCH] mm: dirty_exceeded speedup 
Ravikiran reports that this variable is bouncing all around nodes on NUMA
machines, causing measurable performance problems.  Fix that up by only
writing to it when it actually changed.

And put it in a new cacheline to prevent it sharing with other things (this
happened).
