27	  or Write-after-Read (WAR) violations.  This option is ignored if you

35	  The Virtual Hash Page Table (VHPT) enhances virtual address
36	  translation performance.  Normally you want the VHPT active but you
37	  can select this option to disable the VHPT for debugging.  If you're
38	  unsure, answer N.

45	  compare-and-exchange instructions.  This is slow!  Itaniums

54	  and restore instructions.  It's useful for tracking down spinlock
55	  problems, but slow!  If you're unsure, select N.
