Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Merge crypto tree to pick up scompress and ahash fixes.  The
scompress fix becomes mostly unnecessary as the bugs no longer
exist with the new acompress code.  However, keep the NULL assignment
in crypto_acomp_free_streams so that if the user decides to call
crypto_acomp_alloc_streams again it will work.
