I would simply keep this rtems_cache_invalidate_entire_instruction() and add 
not additional function.  What can be dangerous here?  This SMP cache message 
stuff should be optional in the cache manager implementation (e.g. similar to 
CPU_CACHE_SUPPORT_PROVIDES_RANGE_FUNCTIONS) since on decent SMP processors the 
hardware will ensure this automatically.
