Yeah, sorry, I misremembered what IRQF_DISABLED does.  As Domen pointed 
out, you need to pass myirq, not 74, to request_irq().

void CreateGPIOHandler()
{

	unsigned int myirq=irq_create_mapping(NULL,74);
	enable_irq(74);
	printk("myirq is : %d \n",myirq);
	int ret;

	ret=- request_irq(74, GPIOinterrupt_handler,0, "GPIO", NULL);
	printk("ret is : %d \n",ret);
	

}

Even if IRQF_DISABLED did do what I thought it did (I was thinking of 
IRQ_NOAUTOEN, which is apparently an ARM-only thing), you should never 
call enable_irq() before request_irq(), or without previously disabling 
it (either explicitly or via IRQ_NOAUTOEN).
