Since tfm contexts can contain arbitrary types we should provide at least natural alignment (__attribute__ ((__aligned__))) for them. In particular, this is needed on the Xscale which is a 32-bit architecture with a u64 type that requires 64-bit alignment. This problem was reported by Ronen Shitrit. The crypto_tfm structure's size was 44 bytes on 32-bit architectures and 80 bytes on 64-bit architectures. So adding this requirement only means that we have to add an extra 4 bytes on 32-bit architectures. On i386 the natural alignment is 16 bytes which also benefits the VIA Padlock as it no longer has to manually align its context structure to 128 bits.
