Powerpc has sparse node numbering, i.e. on a 4 node system nodes are

Interesting thing to play with, I'll try to test it on my POWER7 box,
but it doesn't have the OPAL layer :(
Thanks for your interest. I have pushed the patches to
https://github.com/ktraghavendra/linux/tree/serialnuma_v1 if it makes
patches easy to grab.
Note that it's also interesting to try it under PowerVM, with odd NUMA
topologies and report any issues found :)
Thanks Nish, I 'll also grab a powerVM and test.
