+Description: Cache id
+ The id identifies a hardware cache of the system within a given
+ cache index in a set of cache indices. The "index" name is
+ simply a nomenclature from CPUID's leaf 4 which enumerates all
+ caches on the system by referring to each one as a cache index.
+ The (cache index, cache id) pair is unique for the whole
+ system.
+ Currently id is implemented on x86. On other platforms, id is
+ not enabled yet.
