Routine Description:
This function is called to start the next processor.
Arguments:
LoaderBlock - Supplies a pointer to the loader parameter block.
ProcessorState - Supplies a pointer to the processor state to be
used to start the processor.
Return Value:
If a processor is successfully started, then a value of TRUE is
returned. Otherwise a value of FALSE is returned. If a value of
TRUE is returned, then the logical processor number is stored
in the processor control block specified by the loader block.
