+ IA-64 identity-mapped regions use a large page size called "granules".
+ Select "16MB" for a small granule size.
+ Select "64MB" for a large granule size. This is the current default.

+ depends on DEBUG_KERNEL
+ help
+ Selecting this option prints more information for Illegal Dependency
+ Faults, that is, for Read-after-Write (RAW), Write-after-Write (WAW),
+ or Write-after-Read (WAR) violations. This option is ignored if you
+ are compiling for an Itanium A step processor
+ (CONFIG_ITANIUM_ASTEP_SPECIFIC). If you're unsure, select Y.
+ bool "Disable VHPT"
+ depends on DEBUG_KERNEL
+ help
+ The Virtual Hash Page Table (VHPT) enhances virtual address
+ translation performance. Normally you want the VHPT active but you
+ can select this option to disable the VHPT for debugging. If you're
+ unsure, answer N.
+ bool "Turn on compare-and-exchange bug checking (slow!)"
+ depends on DEBUG_KERNEL
+ help
+ Selecting this option turns on bug checking for the IA-64
+ compare-and-exchange instructions. This is slow! Itaniums
+ from step B3 or later don't have this problem. If you're unsure,
+ select N.
+config IA64_DEBUG_IRQ
+ bool "Turn on irq debug checks (slow!)"
+ depends on DEBUG_KERNEL
+ help
+ Selecting this option turns on bug checking for the IA-64 irq_save
+ and restore instructions. It's useful for tracking down spinlock
+ problems, but slow! If you're unsure, select N.
