6684af458bSBrian King	  to reduce the memory size of the system. This is accomplished
6784af458bSBrian King	  by allocating pages of memory and put them "on hold". This only
6884af458bSBrian King	  makes sense for a system running in an LPAR where the unused pages
6984af458bSBrian King	  will be reused for other LPARs. The interface allows firmware to
