Stack switch is required by Stack Guard feature. Following two PCDs are introduced to simplify the resource allocation for initializing stack switch. gUefiCpuPkgTokenSpaceGuid.PcdCpuStackSwitchExceptionList gUefiCpuPkgTokenSpaceGuid.PcdCpuKnownGoodStackSize PcdCpuStackSwitchExceptionList is used to specify which exception will have separate stack for its handler. For Stack Guard feature, #PF must be specified at least. PcdCpuKnownGoodStackSize is used to specify the size of knwon good stack for an exception handler. Cpu driver or other drivers should use this PCD to reserve new stack memory for exceptions specified by above PCD.
