453 | Selects whether support for the IA-64 performance monitor hardware | |
454 | is included in the kernel. This makes some kernel data-structures a | |
455 | little bigger and slows down execution a bit, but it is generally | |
456 | a good idea to turn this on. If you're unsure, say Y. | |

460 | help | |
461 | If you say Y here, you are able to get PAL (Processor Abstraction | |

463 | about the processors in your systems, such as cache and TLB sizes | |

466 | To use this option, you have to ensure that the "/proc file system | |
