I'm curious about what the original poster (Brian Simper) needed
psrinfo for. Doing "cat /proc/cpuinfo" provides information on the
number, types, and speeds of the processors, but it does not tell you
how long they've been online. I don't know of any provisions for
taking them offline though, so it would seem reasonable to use
whatever value uptime reports for all of them.
