Atop patches

[John Johansen]

The server team has requested that we look at including the atop patches
as part of the kernel.

This is a nice to feature, but not a requirement.  I pulled the patches
down but haven't had time to build and test them yet.  If anyone else
has some spare cycles, and can beat me to it the server team would
greatly appreciate it.
