52*84af458bSBrian King	  memory than physically available and will allow firmware to

60*84af458bSBrian King	  Select this option, if you want to enable the kernel interface
61*84af458bSBrian King	  to reduce the memory size of the system. This is accomplished
62*84af458bSBrian King	  by allocating pages of memory and put them "on hold". This only
63*84af458bSBrian King	  makes sense for a system running in an LPAR where the unused pages
64*84af458bSBrian King	  will be reused for other LPARs. The interface allows firmware to
65*84af458bSBrian King	  balance memory across many LPARs.
