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.

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

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,
49 select N.

55 Selecting this option turns on bug checking for the IA-64 irq_save

57 problems, but slow! If you're unsure, select N.
