CRYPTO_SERPENT_SSE2_586 should be selecting CRYPTO_CRYPTD.

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 7c926402)

Apparently, NIST is tightening up its requirements for FIPS validation
with respect to RNGs. Its always been required that in fips mode, the
ansi cprng not be fed key and seed material that was identical, but
they're now interpreting FIPS 140-2, section AS07.09 as requiring that
the implementation itself must enforce the requirement. Easy fix, we
just do a memcmp of key and seed in fips_cprng_reset and call it a day.

v2: Per Neil's advice, ensure slen is sufficiently long before we
compare key and seed to avoid looking at potentially unallocated mem.
