History
Peter Wemm 7628402b07 Move the shared cp_time array (counts %sys, %user, %idle etc) to the 
per-cpu area.  cp_time[] goes away and a new function creates a merged
cp_time-like array for things like linprocfs, sysctl etc.  The
atomic ops for updating cp_time[] in statclock go away, and the scope
of the thread lock is reduced.

sysctl kern.cp_time returns a backwards compatible cp_time[] array.
A new kern.cp_times sysctl returns the individual per-cpu stats.

I have pending changes to make top and vmstat optionally show per-cpu
stats.

I'm very aware that there are something like 5 or 6 other versions "out
there" for doing this - but none were handy when I needed them.

I did merge my changes with John Baldwin's, and ended up replacing a
few chunks of my stuff with his, and stealing some other code.
