Herbert Xu f10b7897ee [CRYPTO] api: Align tfm context as wide as possible
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.
