Async IPsec is in David Miller's .25 tree.

The s390 supports crypto and hashing in one single operation as well.
Take a look on [1] for hasing and [2] crypto. Evgeniy made a HW driver
for the async API [3] which sould be in .25.

[1] linux 2.6.23 arch/s390/crypto/sha1_s390.c
[2] linux 2.6.23 arch/s390/crypto/aes_s390.c
