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
[http://lkml.org/lkml/2001/3/17/55], but don't think they made in ..
