Subject: [246/262] net: Align AF-specific flowi structs to long

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Ward <david.ward@...mit.edu>

commit 728871bc05afc8ff310b17dba3e57a2472792b13 upstream.

AF-specific flowi structs are now passed to flow_key_compare, which must
also be aligned to a long.
