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.

25 depends on DEBUG_KERNEL
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

44 depends on DEBUG_KERNEL
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,
52 bool "Turn on irq debug checks (slow!)"
53 depends on DEBUG_KERNEL
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.
