Delete _ISR_Enable_on_this_core(), _ISR_Flash_on_this_core(), _ISR_SMP_Disable(), _ISR_SMP_Enable(), _ISR_SMP_Flash(). The ISR disable/enable interface has no parameter to pass a specific object. Thus it is only possible to implement a single global lock object with this interface. Using the ISR disable/enable as the giant lock on SMP configurations is not feasible. Potentially blocking resource obtain sequences protected by the thread dispatch disable level are subdivided into smaller ISR disabled critical sections. This works since on single processor configurations there is only one thread of execution that can block. On SMP this is different (image a mutex obtained concurrently by different threads on different processors). The thread dispatch disable level is currently used as the giant lock. There is not need to complicate things with this unused interface.
