[PATCH 0/4] Switch remaining algorithms to shash

This series converts the remaining hash algorithms to use the new shash
interface.

The first patch removes the message schedule W from struct sha512_ctx
since it gets calculated anew on each execution of sha512_transform. This
reduces the size of sha512_ctx considerably and will allow it to be
registered as a shash algorithm (it will pass the size check in
crypto_register_shash (crypto/shash.c:490)).
Herbert, could you explain why descsize must be smaller (or equal)
than PAGE_SIZE / 8?

The next two patches switch sha512 and wp512 to the new shash interface.

The fourth patch is another try to convert michael_mic. The key values
l and r are duplicated in the descriptor part since they are used and
changed during the actual transformation. I would be gratefull for
comments on this patch since I am not sure it's the proper way to do it.
