The reason doing this is that we found that calling StartupAllAps() to flush TLB for all APs in CpuDxe driver after changing page attributes will spend a lot of time to complete. If there are many page attributes update requests, the whole system performance will be slowed down explicitly, including any shell command and UI operation. The solution is removing the flush operation for AP in CpuDxe driver and let AP flush TLB after woken up.
