102 * code that implements the APIs for the same, provide for
103 * registering EDAC type devices which are NOT standard memory.

David Mackey15ed1032012-04-17 11:30:52 -0700107 * Core CPU switches

112 *
David Mackey15ed1032012-04-17 11:30:52 -0700113 * It allows for a 2 level set of hierarchy. For example:
Douglas Thompsone27e3da2007-07-19 01:49:36 -0700114 *
115 * cache could be composed of L1, L2 and L3 levels of cache.

117 * L2 and maybe L3 caches.
118 *
