Subject: Re: Crypto Update for 4.1

Hello,

Commit e68410ebf62676dfb93aafff7c55b76644f37072 in Linus's tree from
this crpyto update (crypto: x86/sha512_ssse3 - move SHA-384/512 SSSE3
implementation to base layer) causes a GPF on boot in
sha512_ssse3_finup for me on a Broadwell i7-5600U, rendering the
kernel unbootable.

Reverting that commit enables me to boot.  I don't know enough about
the code to comment.  Config is attached, and I can provide a photo of
the reported Call Trace if thats helpful.  It is quite reproducible
for me.

yours,
Bobby
