/**
 * Provided for memory components that don't provide an asynchronous
 * method for determining if memory mappings have changed.  If a
 * component only has a synchronous / interactive method of checking,
 * then it can override this macro with some logic to do a (hopefully)
 * cheap check to see if memory mappings have changed.  The intent is
 * that if this cheap check returns true, the upper layer will then
 * invoke the memoryc_process() function to actually process what
 * changed.  This function will be invoked by the upper layer with the
 * syntax:
 *
 * if (opal_memory_changed()) { ... }
 *
 * Hence, if you need any kind of sophisticated logic, you might want
 * to put it in an inline function and have the #define call the
 * inline function.
