  	  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.

  config IA64_PRINT_HAZARDS
  	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.
