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
