SMP race condition on startup with patch clarification

[D.J. Barrow]

This could also be done by
leaving init_idle as an init function

& doing a check in all 
the cpu_idle functions in arch/process.c

#ifdef CONFIG_SMP
if(smp_processor_id()!=0)
#endif
	init_idle();

This would save it attempting to
call the init_idle function 
the second time on the boot processor after
it has been freed by free_initmem & avoid the crash.

This patch however would be much bigger
& affect all the arches & probably would
upset more people.
