  19           on logically-partitioned pSeries systems which use shared

  55           Select this option to enable shared memory partition support.
  56           With this option a system running in an LPAR can be given more
  57           memory than physically available and will allow firmware to
  58           balance memory across many LPARs.

  64         help
  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
  70           balance memory across many LPARs.
