Lets keep the counters to a mininum. If we can calculate the values from
something else then there is no justification for a new counter.

A new counter increases the size of the per cpu structures that exist for
each zone and each cpu. 1 byte gets multiplies by the number of cpus and
that gets multiplied by the number of zones.
