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