-config COMPCACHE_ENABLE
-	bool "enabled on boot"
-	default n
-	help
-	  Enables compressed ram swap devices.
-
-config COMPCACHE_RAM_REPORTED
-	string "swap space reported to kernel in kb"
-	default "2048"
-	help
-	  This is the amount of memory that will be reported 
-	  to the kernel as swap. The real ram in use will differ, 
-	  because of lzo compression.
-	  Example:
-	    16 MB = 2048 KB 
-	    32 MB = 4098 KB
-
-config COMPCACHE_BACKUP_DEV
-	string "Backup device for compcache"
-	default ""
-	help
-	  Compcache will use this as a backup device for swap.
-	  Example:
-	         /dev/sda5
