3.2.69-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "Eric W. Biederman" <ebied...@xmission.com>
commit c9974ad4aeb36003860100221a594f3c0ccc3f78 upstream.
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.

[bwh: Backported to 3.2: use only dev_kfree_skb() and not dev_consume_skb_any()]
