  • Patch adds LRW support for serpent-sse2 by using lrw_crypt(). Patch has been
    tested with tcrypt and automated filesystem tests.

  • Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler
    functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations
    in parallel to improve performance on out-of-order CPUs). Glue code is based
    on one from AES-NI implementation, so requests from irq context are redirected
    to cryptd.

    v2:
    - add missing include of linux/module.h
    (appearently crypto.h used to include module.h, which changed for 3.2 by
    commit 7c926402a7e8c9b279968fd94efec8700ba3859e)
