[PATCH] mm/Kconfig: give DISCONTIG more help text 



This gives DISCONTIGMEM a bit more help text to explain what it does, not just
when to choose it.

	  This option provides enhanced support for discontiguous

	  memory systems, over FLATMEM.  These systems have holes

	  in their physical address spaces, and this option provides

	  more efficient handling of these holes.  However, the vast

	  majority of hardware has quite flat address spaces, and

	  can have degraded performance from extra overhead that

	  this option imposes.



	  Many NUMA configurations will have this as the only option.



	  If unsure, choose "Flat Memory" over this option.
