In current MP implementation, BSP and AP shares the same exception
configuration. Stack switch required by Stack Guard feature needs that BSP
and AP have their own configuration. This patch adds code to ask BSP and AP
to do exception handler initialization separately.
Since AP is not supposed to do memory allocation, all memory needed to
setup stack switch will be reserved in BSP and pass to AP via new API
EFI_STATUS
EFIAPI
InitializeCpuExceptionHandlersEx (
IN EFI_VECTOR_HANDOFF_INFO *VectorInfo OPTIONAL,
IN CPU_EXCEPTION_INIT_DATA *InitData OPTIONAL
);
Following two new PCDs are introduced to configure how to setup new stack
for specified exception handlers.
