numa: Keep track of NUMA nodes present on the command-line
Based on "enable sparse node numbering" patch from Nishanth Aravamudan, but without the code to actually support sparse node IDs. This just adds the code to keep track of present/non-present nodes on the command-line, without changing any behavior.
