2aa107c0aa UefiCpuPkg: Replace Opcode with the corresponding instructions. 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3790

Replace Opcode with the corresponding instructions.
The code changes have been verified with CompareBuild.py tool, which
can be used to compare the results of two different EDK II builds to
determine if they generate the same binaries.

ebfe2d3eb5 UefiCpuPkg/CpuDxe: Fix boot error 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3084

When DXE drivers are dispatched above 4GB memory in 64bit
mode, the address setCodeSelectorLongJump in stack will
be override by parameter. Jump to Qword is not supported
by some processors. So use "o64 retf" instead.

089285b42c Revert "UefiCpuPkg/CpuDxe: Fix boot error" 
This reverts commit cee5b0441a.

Commit cee5b0441a ("UefiCpuPkg/CpuDxe: Fix boot error", 2020-12-08)
breaks CpuDxe (and with it, OVMF boot) on AMD processors. AMD processors
cannot do far jumps to 64-bit targets, as documented in the AMD64
Architecture Programmer's Manual.

Revert the patch until a RETFQ-based substitute is posted.

fab82c1873 UefiCpuPkg/CpuDxe: Add stackless assembly AP entry points 
The AP startup code simply jumps into this code with the CpuDxe driver
without setting up a stack for the processor.

Therefore, this code must setup the stack before calling into C code.

This is the basic flow:
* AP enters CpuDxe driver code (AsmApEntryPoint) without stack
  - AP grabs a lock
  - AP sets up stack
  - AP calls CpuMp.c:ApEntryPointInC
  - If ApEntryPointInC returns, the lock is freed, and another AP may
    run
  - The AP C code may call AsmApDoneWithCommonStack to indicate that
    the AP is no longer using the stack, and another may therefore
    proceed to use the stack and then call ApEntryPointInC
