Currently the implementation will not compile if a SMP BSP is used due to the use of the `rtems_interrupt_enable()` and `rtems_interrupt_disable()` functions (not available in SMP configurations).

It would be good to replace them with `rtems_interrupt_lock_acquire()` and `rtems_interrupt_lock_release()` instead.

You can find a succinct explanation on their differences in the [RTEMS SMP Final Report](http://microelectronics.esa.int/gr740/rtems-smp-final-report-v5.pdf#subsection.3.4).
