Here is a Memory Binding API.  This allows processes to bind themselves to 
particular blocks of memory in a multi-memory block system.  This patch is 
based on top of the Simple Topology API I posted a few moments ago.  The calls 
take a simple bitmask of memblocks.

This is a scaled down version of a full NUMA API I posted several times in the 
past, to a distinct lack of fanfare.  I hope that this smaller patch holds more 
interest to the community...

Enjoy!
