Ard Biesheuvel 508a1c4df0 crypto: simd - correctly take reqsize of wrapped skcipher into account
The simd wrapper's skcipher request context structure consists
of a single subrequest whose size is taken from the subordinate
skcipher. However, in simd_skcipher_init(), the reqsize that is
retrieved is not from the subordinate skcipher but from the
cryptd request structure, whose size is completely unrelated to
the actual wrapped skcipher.

Eric Biggers d14f0a1fc4 crypto: simd - allow registering multiple algorithms at once
Add a function to crypto_simd that registers an array of skcipher
algorithms, then allocates and registers the simd wrapper algorithms for
them.  It assumes the naming scheme where the names of the underlying
algorithms are prefixed with two underscores.

Also add the corresponding 'unregister' function.

Most of the x86 crypto modules will be able to use these.

Martin Kepplinger 1af39daaad crypto: replace FSF address with web source in license notices
A few years ago the FSF moved and "59 Temple Place" is wrong. Having this
still in our source files feels old and unmaintained.

Let's take the license statement serious and not confuse users.

As https://www.gnu.org/licenses/gpl-howto.html suggests, we replace the
postal address with "<http://www.gnu.org/licenses/>".

Herbert Xu 266d051601 crypto: simd - Add simd skcipher helper
This patch adds the simd skcipher helper which is meant to be
a replacement for ablk helper.  It replaces the underlying blkcipher
interface with skcipher, and also presents the top-level algorithm
as an skcipher.
