  47. This option causes SPE local stores to be mapped in process
  48. address spaces using 64K pages while the rest of the kernel
  49. uses 4K pages. This can improve performances of applications
  50. using multiple SPEs by lowering the TLB pressure on them.

  75. Select this, if you want to use the PMI interface
  76. to switch frequencies. Using PMI, the
  77. processor will not only be able to run at lower speed,
  78. but also at lower core voltage.
