/* ARMv7-M interrupt return works by loading a magic value
* into the PC. On real hardware the load causes the
* return to occur. The qemu implementation performs the
* jump normally, then does the exception return when the
* CPU tries to execute code at the magic address.
* This will cause the magic PC value to be pushed to
* the stack if an interrupt occurred at the wrong time.
* We avoid this by disabling interrupts when
* pc contains a magic address.
