+         Select this option, if you want to enable the kernel interface
+         to reduce the memory size of the system. This is accomplished
+         by allocating pages of memory and put them "on hold". This only
+         makes sense for a system running in an LPAR where the unused pages
+         will be reused for other LPARs. The interface allows firmware to
+         balance memory across many LPARs.
