      Jeffrey Lee authored 
      Needed for BCM2835 builds, at least. Guess I should have checked that

      Implement OS_TaskControl 0 · ccd230e7
      Jeffrey Lee authored 
      Add an implementation of RISCOS Ltd's OS_TaskControl 0. In addition to
the documented Select behaviour of resetting the IRQ and SVC stacks,
under RISC OS 5 it resets ABT+UND, and some other important kernel
variables (IRQsema + CDASemaphore)
