  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.

  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,
