Eduardo Habkost 1af878e049 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.

[Initialize max_numa_nodeid to 0 -Eduardo]
[Use MAX() macro when setting max_numa_nodeid -Eduardo]
