  18. on logically-partitioned pSeries systems which use shared
  19. processors, that is, which share physical processors between
  20. two or more partitions.

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

  52. help
  53. Select this option, if you want to enable the kernel interface
  54. to reduce the memory size of the system. This is accomplished
  55. by allocating pages of memory and put them "on hold". This only
  56. makes sense for a system running in an LPAR where the unused pages
  57. will be reused for other LPARs. The interface allows firmware to
  58. balance memory across many LPARs.
