Subject: [PATCH / RFC 0/2] spinlocks fixup in fec / m68knommu driver

I got into this after turning on spinlock debugging.

Jeff: The dev->hard_start_xmit callback is always called from softirq
context so it is save to use spin_lock_irq(), right?

Greg: The isr (fec_enet_rx()) calls three functions. All
but fec_enet_rx() are grabbing the spinlock. Is this on purpose?
