[PATCH 2/2] x86/Kconfig: deprecate DISCONTIGMEM support for 32-bit

[Mike Rapoport]

Mel Gorman says:
  32-bit NUMA systems should be non-existent in practice.  The last NUMA
  system I'm aware of that was both NUMA and 32-bit only died somewhere
  between 2004 and 2007. If someone is running a 64-bit capable system in
  32-bit mode with NUMA, they really are just punishing themselves for fun.

Mark DISCONTIGMEM broken for now and remove it in a couple of releases.
