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.
