Bug#278629: procps: top doesn't handle 2.6 threads %cpu correctly

[Samuel Thibault]

Hi,

Apparently, procps 3.2.5 corrected this somewhat, but it still truncates
CPU usage to 99.9%, which does not make sense in Irix mode (the
default). Here is a patch to correct truncation to 99.9%*#CPUs and fix
format as appropriate. Please apply.

Regards,
Samuel
