+Description:   These files exist in every cpu's cache index directories.
+               There are currently 2 cache_disable_# files in each
+               directory.  Reading from these files on a supported
+               processor will return that cache disable index value
+               for that processor and node.  Writing to one of these
+               files will cause the specificed cache index to be disabled.
+
+               Currently, only AMD Family 10h Processors support cache index
+               disable, and only for their L3 caches.  See the BIOS and
+               Kernel Developer's Guide at
+               http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/31116-Public-GH-BKDG_3.20_2-4-09.pdf
+               for formatting information and other details on the
+               cache index disable.
