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.

26	help
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.

36	help
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.

42config IA64_DEBUG_CMPXCHG
43	bool "Turn on compare-and-exchange bug checking (slow!)"
44	depends on DEBUG_KERNEL
45	help
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.

53	depends on DEBUG_KERNEL
54	help
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.
