	  Select the method of reclaiming virtual memory. Two values

	  are allowed to choose, one is NO_VM_RECLAIM, the other is

	  ENABLE_VMALLOC_SAVING.



	  If you are not absolutely sure what you are doing, leave this

	  option alone.

	bool "Reclaim memory for each subsystem"

	help

	  Enable this config to reclaim the virtual space belonging

	  to any subsystem which is expected to have a lifetime of

	  the entire system. This feature allows lowmem to be non-

	  contiguous.



config NO_VM_RECLAIM

	bool "Do not reclaim memory"

	help

	  Do not reclaim any memory. This might result in less lowmem

	  and wasting some virtual memory space which could otherwise

	  be reclaimed by using any of the other two config options as

	  above.
