From: Herbert Xu Date: Sat, 7 Jan 2006 05:38:15 +0000 (+1100) Subject: [CRYPTO] cipher: Set alignmask for multi-byte loads X-Git-Tag: v2.6.16-rc1~658^2~16 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a429d2609c153882c421b067ad5ae5a38851459e;p=linux-2.6 [CRYPTO] cipher: Set alignmask for multi-byte loads Many cipher implementations use 4-byte/8-byte loads/stores which require alignment on some architectures. This patch explicitly sets the alignment requirements for them.
