In function InitGdt(), SmiPFHandler() and Gen4GPageTable(), it uses CpuIndex * mSmmStackSize to get the SMM stack address offset for multi processor. It misses the SMM Shadow Stack Size. Each processor will use mSmmStackSize + mSmmShadowStackSize in the memory. It should use CpuIndex * (mSmmStackSize + mSmmShadowStackSize) to get this SMM stack address offset. If mSmmShadowStackSize > 0 and multi processor enabled, it will get the wrong offset value. CET shadow stack feature will set the value of mSmmShadowStackSize.
