  28          Enabling this option will make the kernel run more efficiently
  29          on logically-partitioned pSeries systems which use shared
  30          processors, that is, which share physical processors between
  31          two or more partitions.

  61        help
  62          Select this option, if you want to enable support for IO Event
  63          interrupts. IO event interrupt is a mechanism provided by RTAS
  64          to return information about hardware error and non-error events
  65          which may need OS attention. RTAS returns events for multiple
  66          event types and scopes. Device drivers can register their handlers
  67          to receive events.
  68
  69          This option will only enable the IO event platform code. You
  70          will still need to enable or compile the actual drivers
  71          that use this infrastructure to handle IO event interrupts.

  85        help
  86          Say Y here if you want the pseries core to produce a bunch of
  87          debug messages to the system log. Select this if you are having a
  88          problem with the pseries core and want to see more of what is
  89          going on. This does not enable debugging in lpar.c, which must
  90          be manually done due to its verbosity.

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

 108        help
 109          Select this option, if you want to enable the kernel interface
 110          to reduce the memory size of the system. This is accomplished
 111          by allocating pages of memory and put them "on hold". This only
 112          makes sense for a system running in an LPAR where the unused pages
 113          will be reused for other LPARs. The interface allows firmware to
 114          balance memory across many LPARs.

 120          SPLPAR machines can log hypervisor preempt & dispatch events to a
 121          kernel buffer. Saying Y here will enable logging these events,
 122          which are accessible through a debugfs file.
