This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
netpoll can call functions in hard irq context that are ordinarily
called in lesser contexts. For those functions use dev_kfree_skb_any
and dev_consume_skb_any so skbs are freed safely from hard irq
context.
