[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.
