  10           This option enables support for the Sony PS3 game console
  11           and other platforms using the PS3 hypervisor.  Enabling this
  12           option will allow building otheros.bld, a kernel image suitable
  13           for programming into flash memory, and vmlinux, a kernel image
  14           suitable for loading via kexec.

  22         help
  23           This gives you access to some advanced options for the PS3. The
  24           defaults should be fine for most users, but these options may make
  25           it possible to better control the kernel configuration if you know
  26           what you are doing.
  27
  28           Note that the answer to this question won't directly affect the
  29           kernel: saying N will just cause the configurator to skip all
  30           the questions about these options.
  31
  32           Most users should say N to this question.

  40           This option is only for experts who may have the desire to fine
  41           tune the pagetable size on their system.  The value here is
  42           expressed as the log2 of the page table size.  Valid values are
  43           18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.
  44
  45           If unsure, choose the default (20) with the confidence that your
  46           system will have optimal runtime performance.

  53           This option will enable kernel support to take advantage of the
  54           per device dynamic DMA page table management provided by the Cell
  55           processor's IO Controller.  This support incurs some runtime
  56           overhead and also slightly increases kernel memory usage.  The
  57           current implementation should be considered experimental.
  58
  59           This support is mainly for Linux kernel development.  If unsure,
  60           say N.

  95           This support is intended for bootloaders that need to store data
  96           in the repository for later boot stages.
