SVN rev 192304 on 2009-05-18 12:03:43Z by ed
Mark the clock sysctls as MPSAFE.
These sysctls don't need any form of locking. At least cp_times is used
by powerd very often, which means I get 50% less calls to non-MPSAFE
sysctls on my system. The other 50% is consumed by dev.cpu.0.freq, but
this seems to need Giant for Newbus.
