History
Matthew Dillon 80f5c8bf42 Embed a struct vmmeter in the per-cpu structure and add a macro, 
PCPU_LAZY_INC() which increments elements in it for cases where we
can afford the occassional inaccuracy.  Use of per-cpu stats counters
avoids significant cache stalls in various critical paths that would
otherwise severely limit our cpu scaleability.

Adjust all sysctl's accessing cnt.* elements to now use a procedure
which aggregates the requested field for all cpus and for the global
vmmeter.

The global vmmeter is retained, since some stats counters, like v_free_min,
cannot be made per-cpu.  Also, this allows us to convert counters from
the global vmmeter to the per-cpu vmmeter in a piecemeal fashion, so
have at it!
