+Description: Cache id
+
+ The id provides a unique number for a specific instance of
+ a cache of a particular type. E.g. there may be a level
+ 3 unified cache on each socket in a server and we may
+ assign them ids 0, 1, 2, ...
+
+ Note that id value can be non-contiguous. E.g. level 1
+ caches typically exist per core, but there may not be a
+ power of two cores on a socket, so these caches may be
+ numbered 0, 1, 2, 3, 4, 5, 8, 9, 10, ...
