lzeng14 9d00d20ed4 1. Use the check IsAddressValid() to prevent SMM communication buffer overflow in SmmVariable, FtwSmm, FpdtSmm, SmmCorePerformance and SmmBaseHelper, and add check to prevent InfoSize overflows in SmmVariableHandler. 
2. Refine the debug message.
3. Add check to make sure the input VariableName is A Null-terminated string.
4. Use local variable to hold StrSize (VariableName) to avoid duplicated StrSize calculation.

jgong5 ff443d3ebd Use on-demand paging for CpuSaveStates read/write. It was measured about 200us for either read or write the PI CpuSaveStates to framework, ~400us in total on a platform with 80 CPUs with original for loop implementation. So with on-demand paging, if the framework SMI handler doesn’t read/write CpuSaveStates, ~400us will be saved. If the handler happens to use CpuSaveStates, there will be about 20us overhead for either read or write a page which contains 5 continuous CpuSaveStates.
