Hi Jian
Thanks for the patch.
Can we move all IA32 defined data structure or function to MdePkg?
Such as: AsmWriteT

Hi Jian
Thanks for the patch.

Such as: AsmWriteTr, IA32_TASK_STATE_SEGMENT, IA32_TSS_DESCRIPTOR
I am also curious why we use different policy for other boot mode.
Can we use consistent policy?

If Stack Guard is enabled and there's really a stack overflow happened during
boot, a Page Fault exception will be triggered. Because the stack is out of
usage, the exception handler, which shares the stack with normal UEFI driver,
cannot be executed and cannot dump the processor information.
