Subject: [PATCH] xfrm: Apply fix for key lengths for rfc3686(ctr(aes)) to
 2.6.32.y

This fix was applied to 3.0.3, but was not applied to the earlier series. Several
widely-used distros base (or based) their kernels on this series, so the problem
hasn't been fixed for them. The patch below is against 2.6.32.49.

Original commit was 4203223a1aed862b4445fdcd260d6139603a51d9
