Jeff Fan 845c5be1fd UefiCpuPkg/MpInitLib: Program AP stack in fixed address ... Currently, MpInitLib will program AP stack in dynamic address. Each processor will calculate its stack address by adding stack size based on the last stack address. That means AP may have the different stack address everytime it is wakeup by INIT-SIPI-SIPI. When all APs have wakeup to execute AP task, each each has been assigned one stack address. Once the timeout happened on some of APs, BSP will send INIT- SIPI-SIPI to wake up APs. We need to re-assign stack for APs. Based on the current implementation, we might assign one stack address used by other APs. It will cause the unexpected stack overlapped issue. This fix changed the stack assignment policy. We will record the stack address assigned to AP at first time AP wakeup. When AP failed on AP task, BSP could reassigned the same stack for it. Getting initial APIC ID in assembly code could help AP to get saved its stack address.
