     22The low-level start is guided by the per-CPU control state
     23[http://www.rtems.org/onlinedocs/doxygen/cpukit/html/group__PerCPU.html#gabad09777c1e3a7b7f3efcae54938d418 Per_CPU_Control::state].  See also ''_Per_CPU_Change_state()'' and
     24''_Per_CPU_Wait_for_state()''.

     27== Future Directions ==

     29
     30Get rid of ''_CPU_Context_switch_to_first_task_smp()'' and use
     31''_CPU_Context_restore()'' instead since this complicates things.  This function is only specific on SPARC other architectures like ARM or PowerPC do not need it.  The low-level initialization code of secondary processors can easily set up the processor into the right state.
