+          Select this to enable LZO compression for register caches.
+          This will allow machine or CODEC drivers to compress register
+          caches in memory, reducing the memory consumption at the
+          expense of performance.  If this is not present and is used
+          the system will fall back to uncompressed caches.
+
+          Usually it is safe to disable this option, where cache
+          compression in used the rbtree option will typically perform
+          better.
