Chen, Thanks your updating. I attached one addition updating based on you're the latest patches. Please evaluate and sync it into your patches.
BTW, please delete ApStartup.asm from CpuDxe, it seems to be one dummy file. Thanks!

V3-V3.1: 1. use AcquireSpinLockOrFail() intead of AcquireSpinLock() to avoid ASSERT sugguested by Jeff. V2-V3: 1. rebase codes due to Jordan'tree updated: https://github.com/jljusten/edk2/tree/ap-startup-example 2. add supported on Ia32 arch 3. add a new Lock to replace present SpinLock mechanisms in mutilple processors, maybe the SpinLock mechanisms is not MP safe. 4. add function header 5. add StartupAllAPs() supported 6. add SwitchBSP() function, which is unsupported. V1-V2: 1. do not call anything EFI API from APs. 2. add AP busy-wait for task assignment from BSP and get rid of IPI sent mechanism.
