+Description: Disable L3 cache indices
+
+ These files exist in every CPU's cache/index3 directory. Each
+ cache_disable_{0,1} file corresponds to one disable slot which
+ can be used to disable a cache index. Reading from these files
+ on a processor with this functionality will return the currently
+ disabled index for that node. There is one L3 structure per
+ node, or per internal node on MCM machines. Writing a valid
+ index to one of these files will cause the specificed cache
+ index to be disabled.
+
+ All AMD processors with L3 caches provide this functionality.
+ For details, see BKDGs at
+ http://developer.amd.com/documentation/guides/Pages/default.aspx
