+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.
