Jeff / Tejun / Alan, I'm trying to sort out the spinlocks in sata_mv. In some places, the existing code uses ap->lock. But in others, notably the interrupt handling, it uses ap->host->lock. This looks buggy to me, and I'm wondering how to make it bulletproof.
Look closely, there is only one lock. ata_port does not have a spinlock, just a pointer...
