overwrites unallocated memory in the following memset() because
I used the wrong buffer length.

e559e91cce [CRYPTO] api: Allow ablkcipher with no queues
Evgeniy's hifn driver and probably mine don't use ablkcipher->queue at all. 
The show method of ablkcipher will access this field without checking if it 
is valid.

ca7c39385c [CRYPTO] api: Handle unaligned keys in setkey
setkey() in {cipher,blkcipher,ablkcipher,hash}.c does not respect the
requested alignment by the algorithm. This patch fixes it. The extra
memory is allocated by kmalloc() with GFP_ATOMIC flag.

b5b7f08869 [CRYPTO] api: Add async blkcipher type
This patch adds the mid-level interface for asynchronous block ciphers.
It also includes a generic queueing mechanism that can be used by other
asynchronous crypto operations in future.
