+   * The following declares the a smp spinlock to be used to control
typo: s/the a/a

+  SCORE_EXTERN SMP_lock_spinlock_nested_Control
_Thread_Dispatch_smp_spin_lock;
I'm not sold on the name, unless this is the only lock that will be associated
with any _Thread_Dispatch handler.  We should develop a consistent convention
for lock names.

cpukit/score/inline/rtems/score/thread.inl:
Function prototypes should be in .h files. Why aren't these functions inline in
the SMP version?

_Thread_Dispatch_set_disable_level(): This function confuses me. Why looping up
and then down?
