    It seems that some module dependency was lost,
    dm-crypt with async crypto depends now on crypto_blkcipher module
    for this configuration.

    Herbert, any following change required for dm-crypt or it is only
    crypto subsystem issue?
    (With old kernel/dm-crypt it loads "blkcipher" not "crypto_blkcipher",
    maybe some initramdisk change required too...)
