recall the control, but something like this should be used before
executing the SVCall so that it vectors directly to the SVC
handler.
Another, more standard option would be to use interrupt priority
levels to control interrupts. In that case, (1) The SVC would
be the highest priority interrupt (0), (2) irqsave() would set
the interrupt mask level to just above that, and (2) irqrestore
would restore the interrupt level. This would not be diffult,
but does affect a lot of files!
