Now that version 1.7 errata A of the PI spec has finally been released, we can take another look at this series, which incorporates the new MM communicate2 protocol definition, updates the producers for conventional SMM and standalone MM, and updates the variable store components to consume the new version of the protocol. This solves a long standing compatibility issue which made standalone MM fundamentally incompatible with a virtually remapped address space as installed by SetVirtualAddressMap().
