          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.

        bool "Print possible IA-64 dependency violations to console"
        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.

config DISABLE_VHPT
        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.

config IA64_DEBUG_CMPXCHG
        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.
