+///   Dynamically built pointer where a NULL is checked before execution
+///   If NULL (the SBE case), return
+///   Else call the function at the pointer;
+///   pointer is filled in by STOP image build
+///   Run-time updates from Host code that are put on the core image by
+///   STOP API calls
+///     Restore Hypervisor, Host PRD, etc. SCOMs
