Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
This updates the sha512 fix so that it doesn't cause excessive stack
usage on i386. This is done by reverting to the original code, and
avoiding the W duplication by moving its initialisation into the loop.
As the underlying code is in fact the one that we have used for years,
I'm pushing this now instead of postponing to the next cycle.
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: sha512 - Avoid stack bloat on i386
crypto: sha512 - Use binary and instead of modulus
