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