I'm not sure about a negative default value for an unsigned field (affinity).
Can we use something else like MAX_CPUS or something? This isn't a big deal to

+int _Thread_SMP_RR_Next_CPU = 0;
This variable does not appear to need to be globally scoped. Please consider
making it static and putting it in the scope of the find_CPU function.

+int _Thread_SMP_Find_CPU(int cpu)
If this function is solely a helper function for Initialize, please consider
making it static.  Also, the name should be _Thread_SMP_find_CPU. If it is not
a helper function, then its prototype should be declared in thread.h

+#ifdef RTEMS_SMP
+  the_thread->core                    = _Thread_SMP_Find_CPU(affinity);
Why not just add these lines after the call to _Thread_Initialize where it gets
used? Better yet would be to add an interface for assigning affinity to
threads. _Thread_SMP_get/set/initialize_affinity( ); would be my suggestion.
