And if we want to use qemu_allocate_irq here, it will be something like:

cpu_exit_irq = g_new(qemu_irq, 1);
cpu_exit_irq[0] = qemu_allocate_irq(cpu_request_exit, NULL, 0);
DMA_init(0, cpu_exit_irq);

This is what exactly qemu_allocate_irqs does.

Or we modify the DMA_init to make it take qemu_irq as parameter not 
qemu_irq *
