Wrong patch ? This one won't apply, it seems to be already

ok these patches ought to fix this for real (sorry I don't have this

I hope you have time to test these..

Subject: lockdep: core, add enable/disable_irq_irqsave/irqrestore() APIs

Introduce the disable_irq_nosync_lockdep_irqsave() and enable_irq_lockdep_irqrestore() APIs.
These are needed for NE2000; basically NE2000 calls disable_irq and enable_irq as locking
against the IRQ handler, but both in cases where interrupts are on and off. This means that
lockdep needs to track the old state of the virtual irq flags on disable_irq, and restore these
at enable_irq time.

Subject: lockdep: annotate the ne2000 driver with the new disable_irq API addition

The ne2000 driver's xmit function gets called from netpoll with the
_xmit_lock spinlock held as _irqsave. This means the xmit function needs to preserve this
irq-off state throughout to avoid deadlock. It does, but we need to also tell lockdep that
the function indeed does this by using the proper disable_irq annotation.
