	  This option allows you to change some of the ways that
	  Linux manages its memory internally.  Most users will
	  only have one option here: FLATMEM.  This is normal
	  and a correct option.

	  If unsure, choose this option over any other.

	bool "Discontigious Memory"
	depends on ARCH_DISCONTIGMEM_ENABLE
	help
	  If unsure, choose "Flat Memory" over this option.

# Both the NUMA code and DISCONTIGMEM use arrays of pg_data_t's
