Hi tglx,

My system is arm, and I connect SDIO WiFi card.
In fact, I use kernel 3.18.11 base. But, I think sources concerned
with this are same. 

This is my "/proc/interrupts".

           CPU0       CPU1       CPU2       CPU3
 46:      20672          0          0          0       GIC  46  mmc1

In drivers/irqchip/irq-gic.c:gic_set_type(), irq46 is set as
IRQ_TYPE_LEVEL_HIGH.

Best regards,
 Kohji Okuno
