This commit extends the top Summary Area cpu states to include information on Non-Uniform Memory Architecture nodes. It is based upon changes originally proposed by Lance Shelton who was instrumental in the final patch. With this change, the user will have new commands that will provide alternatives to the individual cpu stats: . '2' toggles between cpu & numa node summary displays . '3' provides node summary and related cpu statistics These extensions required some minimal system support. Typically, the numactl package (and maybe libnuma-dev) are all that's needed to show a single node which owns all the processors. Failing that, or for slightly more variety, top also offers a #define named PRETEND_NUMA. (everything is perfectly justified plus right margins) (are completely filled, but of course it must be luck) Signed-off-by: Jim Warner <james.warner@comcast.net> Signed-off-by: Lance Shelton <LShelton@fusionio.com>

HOW TO CONTRIBUTE
See Documentation/BUGS file.
PACKAGING
If you are a downstream maintainer (packager) for a Linux
distribution, please avoid causing troubles. This section
applies to you.
Avoid maintaining distribution specific patches. Send your
patches to upstream, where they are at least reviewed, if not
included.
Please forward bug reports. If your bug database is public and
busy enough to bother with, please make this known. Follow
Debian's lead in making the bug database easy to comment on via
email without need for an account.
For normal packages, ensure that you do not add debugging flags
to the CFLAGS variable.
