Shreyas, can you provide a proper fix for this bug (see
http://www.spinics.net/lists/netdev/msg189554.html for details).

As far as I understand it you can not claim a fake transport layer header
size for udp and blindly check the available buffer size through
pskb_may_pull later. With a 32 bits HIGHMEM guest config (yuck...) it ends
up enabling bh within a network device start_xmit context.
