The idle time reported in /proc/uptime (2nd field) seems to be the idle
time of only CPU0. Shouldn't it reflect the total idle time on a SMP system?
Do folks agree that it is a bug that needs to be fixed? If so, will send
a patch ...
Fyi, I see patches submitted to fix this way back in 2001

On further reflection, it doesn't sound buggy. Reporting idle time across all
cpus in /proc/uptime will cause idle time > uptime, which will be odd. I
guess if anyone wants strict idle time from all cpus, they can always
look at /proc/stat.
