A protocol with a single, interleaved shared L2 cache where directory
state of L1 sharers is stored in the L2 tags.  Single CMP only.

A 2-level directory protocol.  Supports Multiple-CMP configurations.
Directory state at the second level is at memory.  Directory state at
the first level, to track L1 sharers, is at the interleaved L2 bank.

Broadcast snooping protocol that relies on an ordered switch.
