Agreed.
Right now, if the (socket,core) stuff is unavailable, you'll get a
graceful failure from all the topology functions.
Is it possible to have less than all of the (socket,core)
information, the node ID information, and HTT information? Do we
need to make the have_topo_information() function a bit more fine-
grained? (i.e., indicate which, if any, of the topology information
is available) And/or make *some* of the functions fail (gracefully)
if the requested information is unavailable?
I do not follow the history of the Linux kernel enough to know when
this stuff was introduced, nor what distros are doing to back port, etc.
