OK, I applied the original patch here, along with this on top of it:
IPoIB: Use spin_lock_irq() instead of spin_lock_irqsave()
We know ipoib_flush_paths() is called from plain process context with
interrupts enabled, since it does wait_for_completion(). So there's
no need to use spin_lock_irqsave() -- spin_lock_irq() is fine.
