xfrm: alg_key_len & alg_icv_len should be unsigned
In commit ba749ae98d5aa9d2ce9a7facde0deed454f92230 ([XFRM]: alg_key_len should be unsigned to avoid integer divides <http://git2.kernel.org/?p=linux/kernel/git/davem/net-2.6.git;a=commitdiff;h=ba749ae98d5aa9d2ce9a7facde0deed454f92230>) alg_key_len field of struct xfrm_algo was converted to unsigned int to avoid integer divides. Then Herbert in commit 1a6509d991225ad210de54c63314fd9542922095 ([IPSEC]: Add support for combined mode algorithms) added a new structure xfrm_algo_aead, that resurrected a signed int for alg_key_len and re-introduce integer divides. This patch avoids these divides and saves 64 bytes of text on i386. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
