/**
+ Worker function to execute a caller provided function on all enabled APs.
+
+ @param[in] Procedure A pointer to the function to be run on
+ enabled APs of the system.
+ @param[in] SingleThread If TRUE, then all the enabled APs execute
+ the function specified by Procedure one by
+ one, in ascending order of processor handle
+ number. If FALSE, then all the enabled APs
+ execute the function specified by Procedure
+ simultaneously.
+ @param[in] WaitEvent The event created by the caller with CreateEvent()
+ service.
+ @param[in] TimeoutInMicrosecsond Indicates the time limit in microseconds for
+ APs to return from Procedure, either for
+ blocking or non-blocking mode.
+ @param[in] ProcedureArgument The parameter passed into Procedure for
+ all APs.
+ @param[out] FailedCpuList If all APs finish successfully, then its
+ content is set to NULL. If not all APs
+ finish before timeout expires, then its
+ content is set to address of the buffer
+ holding handle numbers of the failed APs.
+
+ @retval EFI_SUCCESS In blocking mode, all APs have finished before
+ the timeout expired.
+ @retval EFI_SUCCESS In non-blocking mode, function has been dispatched
+ to all enabled APs.
+ @retval others Failed to Startup all APs.
