V4->V5
- Split N_MEMORY into N_NORMAL_MEMORY and N_HIGH_MEMORY to support
  32 bit NUMA.
- Mel tested it on 32bit NUMA
- !NUMA Fixes
- Tested on SMP and UP.

V3->V4 (by Lee)
- Add fixes and testing.

V2->V3
- Refresh patches (sigh)
- Add comments suggested by Kamezawa Hiroyuki
- Add signoff by Jes Sorensen

V1->V2
- Add a generic layer that allows the definition of additional node bitmaps

This patchset is implementing additional node bitmaps that allow the system
to track nodes that are online without memory and nodes that have processors.

Note that this patch is only the beginning. All code portions that assume that
an online node has memory must be changed to use either N_NORMAL_MEMORY or
N_HIGH_MEMORY.
