top: raise %CPU maximum if large numbers of processors <=== port of newlib 7279cd8e

______________________________ original newlib message

It would appear that openSUSE was the first to release
procps-ng version 4.0.0 (in the tumbleweed distro). As
a result I checked their source rpm and found a couple
of patches I'm porting to newlib for the next release.

This particulate patch, with some changes, is openSUSE
patch 'procps-ng-3.3.10-large_pcpu.patch'. The changes
were strictly cosmetic. They involved whitespace only.

[ it should be noted that the net effect for raising ]
[ the maximum is to produce a '?' in the %CPU field. ]
[ that's because its width is fixed at five columns. ]
[ but at least the '?' won't distort actual results. ]
