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

14      Select "16MB" for a small granule size.
15      Select "64MB" for a large granule size. This is the current default.

26    help
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.

36    help
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.

44    depends on DEBUG_KERNEL
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.

53    depends on DEBUG_KERNEL
54    help
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
57      problems, but slow! If you're unsure, select N.
