[PATCH] lockdep: annotate forcedeth.c disable_irq()
nv_do_nic_poll() is called from timer softirqs, which has interrupts enabled, but np->lock might also be taken by some other interrupt context. The driver does disable_irq() to get around this problem, so annotate the disable_irq()/enable_irq() calls for lockdep. Has no effect on non-lockdep kernels.
