That's the easy part and I just did it yesterday but I didn't posted it because it's not enough. You have also to clear irqs while reading the active_bhs and to take them cleared until you return from the irq (this in UP and UP is the simple case).
In SMP you also need a spinlock in the middle of do_bottom_half().
I was doing the complete patch now.
