[PATCH] build-sys: in top program, enable NUMA/Node extensions
- From: Jim Warner <james.warner@xxxxxxxxxxx>
- Date: Mon, 8 Apr 2013 00:00:00 -0500
This patch provides the build system support for those
top extensions dealing with the NUMA summary displays.
For providing the initial impetus for this enhancement
I wish to thank Lance Shelton <LShelton@xxxxxxxxxxxx>.
(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
