Andy Wingo 4a9949d7ac [PATCH] raw1394: fix locking in the presence of SMP and interrupts ... Changes all spinlocks that can be held during an irq handler to disable interrupts while the lock is held. Changes spin_[un]lock_irq to use the irqsave/irqrestore variants for robustness and readability. In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're not accessing host_info_list or host_count, and holding this lock while trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in raw1394.c:receive_iso. Test program attached reliably deadlocks all SMP machines I have been able to test without this patch.
