Star Zeng 6e601a4109 UefiCpuPkg PiSmmCpuDxeSmm: Fixed #double fault on #page fault for IA32 ... When StackGuard is enabled on IA32, the #double fault exception is reported instead of #page fault. This issue does not exist on X64, or IA32 without StackGuard. The fix at e4435f710c was incomplete. It is because AllocateCodePages() is used to allocate buffer for GDT and TSS, the code pages will be set to RO in SetMemMapAttributes(). But IA32 Stack Guard need use task switch to switch stack that need write GDT and TSS, so AllocateCodePages() could not be used. This patch uses AllocatePages() instead of AllocateCodePages() to allocate buffer for GDT and TSS if StackGuard is enabled on IA32.
