Use skcipher_givcrypt_cast(crypto_dequeue_request(queue)) instead, which
does the same thing in much cleaner way. The skcipher_givcrypt_cast()
actually uses container_of() instead of messing around with offsetof()
too.

<title>crypto: hash - Add real ahash walk interface</title>

<id>75ecb231ff45b54afa9f4ec9137965c3c00868f4</id>
<content type='text'>
Although the existing hash walk interface has already been used
by a number of ahash crypto drivers, it turns out that none of
them were really asynchronous.  They were all essentially polling
for completion.

That's why nobody has noticed until now that the walk interface
couldn't work with a real asynchronous driver since the memory
is mapped using kmap_atomic.

As we now have a use-case for a real ahash implementation on x86,
this patch creates a minimal ahash walk interface.  Basically it
just calls kmap instead of kmap_atomic and does away with the
crypto_yield call.  Real ahash crypto drivers don't need to yield
since by definition they won't be hogging the CPU.

<title>crypto: user - Fix lookup of algorithms with IV generator</title>

We lookup algorithms with crypto_alg_mod_lookup() when instantiating via
crypto_add_alg(). However, algorithms that are wrapped by an IV genearator
(e.g. aead or genicv type algorithms) need special care. The userspace
process hangs until it gets a timeout when we use crypto_alg_mod_lookup()
to lookup these algorithms. So export the lookup functions for these
algorithms and use them in crypto_add_alg().

As struct skcipher_givcrypt_request includes struct crypto_request
at a non-zero offset, testing for NULL after converting the pointer
returned by crypto_dequeue_request does not work.  This can result
in IPsec crashes when the queue is depleted.

This patch fixes it by doing the pointer conversion only when the
return value is non-NULL.  In particular, we create a new function
__crypto_dequeue_request that does the pointer conversion.

This patch exports the finup operation where available and adds
a default finup operation for ahash.  The operations final, finup
and digest also will now deal with unaligned result pointers by
copying it.  Finally export/import operations are will now be
exported too.

<content type='text'>
This patch changes crypto4xx to use the new style ahash type.
In particular, we now use ahash_alg to define ahash algorithms
instead of crypto_alg.

This is achieved by introducing a union that encapsulates the
new type and the existing crypto_alg structure.  They're told
apart through a u32 field containing the type value.
