12 | IA-64 identity-mapped regions use a large page size called "granules". | |

14 | Select "16MB" for a small granule size. | |

27 | Selecting this option prints more information for Illegal Dependency | |
28 | Faults, that is, for Read-after-Write (RAW), Write-after-Write (WAW), | |
29 | or Write-after-Read (WAR) violations. This option is ignored if you | |
30 | are compiling for an Itanium A step processor | |
31 | (CONFIG_ITANIUM_ASTEP_SPECIFIC). If you're unsure, select Y. | |

37 | The Virtual Hash Page Table (VHPT) enhances virtual address | |
38 | translation performance. Normally you want the VHPT active but you | |
39 | can select this option to disable the VHPT for debugging. If you're | |
40 | unsure, answer N. | |

45 | help | |
46 | Selecting this option turns on bug checking for the IA-64 | |
47 | compare-and-exchange instructions. This is slow! Itaniums | |
48 | from step B3 or later don't have this problem. If you're unsure, | |
49 | select N. | |

55 | Selecting this option turns on bug checking for the IA-64 irq_save | |
56 | and restore instructions. It's useful for tracking down spinlock | |
